This document provides guidelines for the design and construction of bored precast concrete piles used for foundations. It outlines necessary site investigation information needed, equipment used, and design considerations. Bored precast piles involve boring holes and lowering precast concrete piles that are then grouted in place. Proper site data on soil conditions, groundwater levels, and structural loading is required. Equipment for boring, handling, and grouting the piles must be selected based on subsoil properties. Pile design should ensure loads are safely transmitted to the soil without failure or excessive settlement.
Vacuum consolidation method worldwide practice and the lastest improvement ...John Tran
The document discusses vacuum consolidation, a technique for improving soft soils by applying vacuum pressure. It was originally developed in Sweden in the 1950s and has since been applied worldwide. The document summarizes different vacuum consolidation systems used in various countries. It describes typical system components like vertical drains, surface drainage layers, sealing techniques, and vacuum pumps. It also provides examples of vacuum consolidation projects in China, France, Japan, and other countries. The document aims to compare vacuum consolidation practice worldwide and introduce recent improvements in Japan.

Design of earth-retaining structures - Lecture 6Chris Bridges
This document discusses the design of a soil nailed retaining wall for a tunnel project. It provides information on soil nailing including components, applications, advantages and disadvantages. It then presents a case study on the Kedron Park Hotel Tunnels project which required a 30m deep excavation near existing structures. The document outlines the contractor's design for a soil nailed wall with 18m of nails and 10m of piles. It discusses factors considered in the design like tunnelling impacts, modeling techniques, and construction requirements. The adopted wall geometry, sizing of nails, design codes and analysis methods are presented.

Channel routing methods simulate the movement of flood waves through channels using equations like the continuity equation. There are two main types: hydrologic routing which uses empirical relationships between inflow, outflow, and storage, and hydraulic routing which uses the momentum equation to model actual water movement physics more accurately. Common routing methods include Modified Puls, Kinematic Wave, Muskingum, and Muskingum-Cunge, which apply combinations of the continuity, momentum, and other equations to calculate outflow hydrographs from inflow hydrographs.
This document contains information about calculating the storage volume of two reservoirs using different methods.
For the first reservoir:
- The storage volume is calculated as 2.5 Mha-m using the cone, prismoidal, and trapezoidal methods based on area-elevation data ranging from 200-300m in 20m intervals.
For the second reservoir:
- The storage volume is calculated as 1.5 Mha-m using the cone, trapezoidal, and prismoidal methods based on area-elevation data including an interpolated value for 270m elevation.

This document discusses using web tools to aid teaching. The author's goal is to expose teachers to relevant communication and collaboration tools over five days that can help teachers interact with students and families, and engage students through interactive learning materials, teachers, and peers. The author maintains that technology helps with communication and interaction, connecting to students' interests while teaching crucial modern skills, and that practice and time are needed for learning.
Open data and linked open data (LOD) were discussed. LOD involves publishing open data in a linked format using URIs and properties to connect related data. This allows data to be queried and used as a global database. Examples of LOD included DBpedia, which extracts data from Wikipedia and makes it available in multiple languages through SPARQL endpoints. Japanese LOD datasets such as DBpedia Japanese were also presented and can be queried to learn information about topics in Japan.
