A 10 m * 30 m mat foundation is to be built on the surface of a 20 m thick layer of unsatu-rated silty sand. The silty sand is underlain by a stiff bedrock material. The water table is at a great depth. The silty sand is relative uniform and in situ testing indicates it has a constrainedmodulus of 19 MPa. The building applies a uniform stress of 50 kPa at the base of the mat.Compute the settlement under the center of the mat.

Question
A 10 m * 30 m mat foundation is to be built on the surface of a 20 m thick layer of unsatu-
rated silty sand. The silty sand is underlain by a stiff bedrock material. The water table is at a
great depth. The silty sand is relative uniform and in situ testing indicates it has a constrained
modulus of 19 MPa. The building applies a uniform stress of 50 kPa at the base of the mat.
Compute the settlement under the center of the mat.
