QUESTION: 1

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

Solution:

QUESTION: 2

σ_{z} 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)

∴
