Test : Boussinesq’s theory - Question 1

### The problems due to stress distribution in soils due to a concentrated load was studied by ______

Detailed Solution for Test : Boussinesq’s theory - Question 1

Boussinesq in 1885 studied and solved the problems of stress distribution in soils due to a concentrated loads acting at the ground surface. Darcy gave the law of flow of water through soils. The stress function was introduced by G.B Airy in 1862.

Test : Boussinesq’s theory - Question 2

### The assumption of Boussinesq equation is that the soil is ______

Detailed Solution for Test : Boussinesq’s theory - Question 2

Boussinesq solved the problems of stress distribution in soils due to a concentrated loads acting at the ground surface. The assumptions made are based on theory of elasticity. Therefore, the soil is considered to be elastic.

Test : Boussinesq’s theory - Question 5

The Boussinesq influence factor is given by _______

Detailed Solution for Test : Boussinesq’s theory - Question 5

The Boussinesq influence factor is given by,  where the K= Boussinesq influence factor which is a function of r/z ratio which is a dimensionless factor.

Test : Boussinesq’s theory - Question 6

The assumption made by Boussinesq in the solutions is by the ______

Detailed Solution for Test : Boussinesq’s theory - Question 6

Boussinesq in 1885 studied and solved the problems of stress distribution in soils due to a concentrated loads acting at the ground surface, by assuming a suitable stress function. The assumptions made are based on theory of elasticity.

Test : Boussinesq’s theory - Question 7

The assumption of Boussinesq equation is that the soil is _____

Detailed Solution for Test : Boussinesq’s theory - Question 7

Boussinesq solved the problems of stress distribution in soils due to a concentrated loads acting at the ground surface. The assumptions made are based on theory of elasticity. Therefore, the soil is considered to be elastic and of homogeneous nature.
