QUESTION: 1

A line load of infinite length has an intensity q per unit length. What is the vertical stress σat a depth z below the earth at the centre of the load?

Solution:
QUESTION: 2

σz is the vertical stress at a depth equal to z in the soil mass due to a surface point load Q. The vertical stress at depth equal to 2z will be

Solution:

Under the point load, the vertical stress is given by, 

(From Boussinesq’s equation at r/z - 0)
∴
