QUESTION: 1

### A line load of infinite length has an intensity q per unit length. What is the vertical stress σz at 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)
∴ QUESTION: 3

### In a Newmark’s influence chart for stress distribution, there are 10 concentric circles and 50 radial lines. The influence factor of the chart is
