Construction of sheet piles:
Sheet piles are normally driven in three to four sections together and in
sequence as shown below:
Design of sheet piles:
Type of sheet piles based on method of supported
- Cantilever
sheet piles
- Anchored
sheet piles
Design of cantilever sheet pile wall includes two parts:
1.
Design the embed length of sheet pile against rotational failure.
2.
Select the sheet pile section to resist moment and shear:
Commonly assumed failure mode of cantilever and anchored
sheet piles are shown below:
