Ground improvement using vibro-stone technique
This document summarizes the vibro-stone column ground improvement technique. It discusses that stone columns involve installing compacted columns of crushed stone in the ground to improve load bearing capacity and reduce settlement. There are two main installation methods - non-displacement using bored and rammed systems, and displacement using vibro-replacement. The design of stone columns considers factors like column diameter, spacing, replacement ratio, loading patterns, site conditions, and installation technique to meet settlement tolerances. Stone columns function to increase bearing capacity, improve stiffness, carry high loads, and homogenize variable soil properties.

This document discusses mechanisms and mitigation of highway landslides in Indiana. It describes common landslide types such as high bluff peeloffs, groundwater blowouts, deep-seated slides, and shallow colluvial slides. A case study of repeated landslides on State Route 237 is presented. The initial slide was repaired with a soil nail wall, but a second slide occurred. Investigation revealed collapsed coal mine shafts requiring interceptor drains, grouting, and a new drilled pier wall with tiebacks. Constructability concerns led to design changes to safely construct the new wall and mitigate landslide risk.
Ground improvement techniques
The document discusses various ground improvement techniques including dry soil mixing, dynamic compaction, injection systems, rapid impact compaction, rigid inclusions, vibro compaction, vibro concrete columns, vibro piers, and wet soil mixing. It provides details on each technique such as how it is performed, the types of soils it can be used to treat, and examples of how it has been used to improve soil properties like bearing capacity, settlement, and liquefaction potential.
Research in geotechnical engineering
Ground improvement involves altering the properties of soil to better suit engineering project requirements rather than changing the design. This involves reducing settlement, increasing shear strength and bearing capacity, and improving liquefaction resistance. A simple demonstration showed how adding a cloth layer to a pile of sand reduced dispersion, analogous to how geosynthetics can improve soil. Geogrids are polymer meshes that reinforce soil through friction and adhesion. Geotextiles and geogrids can reduce required pavement thickness for roads by improving soil strength properties.
3 Soluble Salt Study
The study evaluated why crop growth is inhibited after removing poultry manure stacks by analyzing soil samples from the stacking site. Soil samples found high levels of soluble salts like ammonium, potassium, and manganese in the top 3 feet of soil that created toxic conditions for seeds. These salts leached out over time, restoring soil productivity. The manure-soil interaction under the stack concentrated ammonium in the top foot. While stacking poses little risk with proper siting and construction, producers should plant salt-tolerant crops initially and establish new crops quickly to remove mobile nutrients.
Grouting
The presentation illustrates a technique for ground improvement, Grouting. In India, grouting is still not being used very much. In this presentation, I have demonstrated the basic types of grouting, goals of ground improvement and two case studies of grouting.
Preparation of CRICKET pitch
The document discusses the preparation of a cricket pitch. It begins by noting a cricket pitch should be dry, firm, and provide even bounce. It then outlines the steps to prepare a new pitch, including:
1. Digging out an area 100ft long and 10ft wide to a depth of 3ft.
2. Laying down layers of ballast stone, bricks, charcoal, and various soil mixtures to create a firm foundation for grass growth.
3. Seeding the pitch with wet grass and maintaining it with regular watering and light rolling over 6 weeks until the grass is 4-6 inches high and the pitch is firm.

Ecolawns for the Pacific Northwest
The document discusses the concept of "ecolawns" as a more sustainable alternative to traditional grass lawns. Ecolawns aim to mimic naturally occurring lawn mixtures by including drought-tolerant grasses and broadleaf plants. Initial trials incorporated perennial ryegrass, yarrow, clovers, and daisies. These ecolawns have stayed green with minimal irrigation and no pesticide use. Further research is still needed to expand the plant palette and commercial availability of ecolawn mixtures tailored to different regions. The goal is to provide low-maintenance lawn options that require fewer inputs than traditional grass lawns.
OGCSA Chapter Meeting, October 18, 2010
This document provides a summary of research and programs at Oregon State University's Turfgrass Management program. It discusses the restructuring of departments within the College of Agricultural Sciences, including the combining of the Horticulture and Crop & Soil Science Departments. Enrollment numbers and courses taught in the turfgrass management program are presented. Several turfgrass research trials conducted by faculty and students are summarized, focusing on anthracnose disease management, water use of cool-season grasses, evaluating the effects of geohumus, seashore paspalum adaptation, and poa annua green speed management.
Fertility Management for Annual Bluegrass
The annual bluegrass fertility trial found that:
1. Adding calcium and sulfur increased soil pH, while sulfur alone slightly decreased pH compared to no additions.
2. Turf quality was generally highest in treatments with moderate nitrogen, phosphorus, potassium, and sulfur additions.
3. Over the course of two years, turf quality averaged from 5.3 to 5.4 out of 7 across different nutrient treatment combinations.
Turf Culture in Shade
This document provides advice on growing lawns in shaded areas. It discusses the challenges of shade, including reduced photosynthesis, competition from tree roots, and debris accumulation from trees. Certain grasses like fine fescues and colonial bentgrass can tolerate partial shade better than Kentucky bluegrass. The document recommends shade-tolerant grass mixes and strategies like tree pruning to increase sunlight. The key is accepting that lawns in heavy shade will be thin and may need to be supplemented with other groundcovers. Overall shade tolerance for lawns depends on the grass species and amount of sunlight received.
Thatch Management
Thatch is a layer of organic material between grass and soil composed mainly of stems and roots. Factors like certain grass species, soil pH, aeration, and nitrogen levels can increase thatch buildup. Dethatching mechanically or biologically can help control thatch. Biological control uses microbes and other organisms to decompose thatch. Key processes include macrofauna ingesting thatch to increase surface area for microbes, microbes secreting enzymes to break down polymers, and secondary microbes further decomposing partially digested material.

Bioretention Site Evaluation and Considerations for Design
This document discusses reasons why bioretention practices fail and considerations for proper site evaluation and design. The top reasons for failure are sediment clogging, undersized cells due to overestimated infiltration, eroding sideslopes, and undersized ponding volumes. Other major causes are construction issues, poor plant selection and maintenance, and lack of pre-treatment. Proper site evaluation considers soil type, depth to bedrock/water table, and drainage area. Pretreatment is required to remove sediment before it reaches the bioretention cell.

Criteria 3 : Soil Conservation
The document discusses strategies for soil conservation during construction projects. It describes how topsoil can be affected by excavation, deforestation, erosion, and paving during construction. Solutions discussed include retaining vegetation cover, properly storing and replacing topsoil, using sediment control measures like silt fencing and basins, contouring land, and afforestation. Stormwater management strategies are also important to prevent soil runoff and erosion. Two case studies of buildings that implemented soil conservation strategies are briefly described.
soil retention in construction -Group 7 powerpoint
Soil retention is important for plant growth, flood control, and soil functioning. Soil texture and composition determine water retention levels, with sandy soils retaining the least and clay soils retaining the most. Soil can hold considerable amounts of water important for plants and organisms. The maximum water soil can hold is field capacity, while the minimum for plant growth is wilting point. Soil water retention impacts the environment, climate, hydrological cycle, and soil stability. Techniques to retain soil include soil nailing, retaining walls, and different types of excavation methods.

DryJect Golf Presentation 2006 11 6 06
The document discusses aerification of golf courses and presents an alternative aerification method called DryJect. Some key points:
1) Traditional core aerification is disruptive to the putting surface and requires the course to be closed for several days for recovery, while DryJect allows aerification with minimal surface disruption and same-day reopening.
2) DryJect injects dry amendments into the soil using compressed air to depths of up to 8 inches, improving soil structure and health below the surface.
3) Profile Porous Ceramic is an amendment that can be used to balance air, water, and nutrients in the soil profile when injected using DryJect. This creates healthier roots and turf

Team #7 Geotechnical Report (2)
The document provides a geotechnical master plan for a proposed residential community called Joy Ranch Housing situated on 622.86 acres. 14 exploratory borings were performed across the site to determine soil characteristics in different parcels. Testing showed predominantly clayey sands near the surface. Groundwater levels were found to be deep, between 301-511 feet below surface. Based on soil testing, design recommendations are provided for structure footings and retaining walls to account for soil properties and planned building loads, including for an elementary school and pedestrian bridge. Issues like collapse, subsidence, fissures and sulfate are also addressed.
Innovative Slope Stabilisation
This document summarizes the design of a retaining structure to stabilize a section of highway affected by slope failures. A combination system using soldier piles, rock anchors, and ground improvement piles was developed to support the road formation and account for varying bedrock depths. Soldier piles were used where bedrock was shallow, and were anchored with rock anchors where overburden was thicker. Ground improvement piles were used where bedrock was deepest. The detailed design specified pile sizes and spacing based on bedrock depth, and rock anchors were installed through soldier piles below road level. This hybrid system provided stabilization while accommodating site conditions in a cost-effective manner.
Babson Court Outfall Restoration
The Babson Court Outfall Restoration Project in Fairfax County, VA restored a 324-foot outfall channel and 66-foot tributary to address erosion and public safety concerns. The restoration incorporated natural stream design techniques like step pools, rock steps, and riffles. It also removed 250 cubic yards of sediment from a dry pond, which was re-vegetated. The project is expected to reduce nitrogen, phosphorus, and suspended solid pollution in stormwater runoff.
