During geological investigation on a site, it was observed that subsoil contains 7.5 m depth of clay followed by some other incompetent layers. The consultant decided to design a friction pile group which should be economical and able to carry the anticipated load of 1.5 x 10° N excluding the weight of pile cap. Design and draw the plan of the most suitable friction pile group considering the following parameters: = 0.030 N/ mm - 2.25 Cohesion intercept of clayey layer Factor of safety against shear failure Weight of pile cap = 110000N Pile diameter 300 mm %3D

Question
During geological investigation on a site, it was observed that subsoil contains 7.5 m
depth of clay followed by some other incompetent layers. The consultant decided to
design a friction pile group which should be economical and able to carry the anticipated
load of 1.5 x 10° N excluding the weight of pile cap. Design and draw the plan of the
most suitable friction pile group considering the following parameters:
= 0.030 N/ mm
- 2.25
Cohesion intercept of clayey layer
Factor of safety against shear failure
Weight of pile cap
= 110000N
Pile diameter
300 mm
%3D
