The document discusses sheet pile structures and their uses in construction. It covers cantilever sheet pile walls and anchored sheet pile walls. Some key points include:
- Sheet piles provide resistance to driving stresses and can be reused on multiple projects. They are lightweight and have a long service life above or below water.
- Cantilever sheet pile walls derive their support from the soil on one side of the wall. Anchored sheet pile walls use anchors to provide additional support from the soil on both sides.
- Failure modes of cantilever sheet piles include elastic deformation and straining actions.
- Design of anchors for sheet piles involves locating the anchor plate in a zone to develop full passive resistance from
5. SHEET PILE STRUCTURE
ADVANTAGES
1. Provides high resistance to driving stresses.
2. Light weight.
3. Can be reused on several projects.
4. Long service life above or below water with modest
protection.
5. Easy to adapt the pile length by either welding or bolting.
6. Joints are less apt to deform during driving
42. DESIGN OF ANCHORS
The resistance offered by an anchor plate or a beam is derived
from the passive resistance of the soil in front of the plate.
For full passive resistance to develop, the anchor plate must be
located in Zone CDE.
Teng gave the following equations for the ultimate resistance of
anchor plates in granular soils located at or near the ground
surface.
Let B be the length of the anchor perpendicular to the cross
section and let h be the height of the anchor.
