Q1:

A point load of 700 kN is applied on the surface of thick layer of clay. Using Boussinesq's elastic analysis, the estimated vertical stress (σv) at a depth of 2 m and a radial distance of 1.0 m from the point of application of the load, is :

A 47.5 kPa

B 47.6 kPa

C 47.7 kPa

D 47.8 kPa

ANS:D - 47.8 kPa
