Test: Stress Distribution in Soil - 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?

Detailed Solution for Test: Stress Distribution in Soil - Question 1

Test: Stress Distribution in Soil - 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

Detailed Solution for Test: Stress Distribution in Soil - Question 2

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