Q1:

The Westergaard analysis is used for

A sandy soils

B cohesive soils

C stratified soils

D clayey soils.

ANS:C - stratified soils

Assumptions:

(1) The soil is elastic and semi-infinite.
(2) Soil is composed of numerous closely spaced horizontal layers of negligible thickness of an infinite rigid material.
(3) The rigid material permits only the downward deformation of mass in which horizontal deformation is zero. Stratified soil means soil which is having different layers also called as layered soil.
