CE 240: Soil Mechanics and Foundations (Fall Semester)

Aims:

1, To describe soil as an engineering material and to understand the nature of stresses induced in the soil and by the soil

2, To give an appreciation of the function and forms of shallow and deep foundations.

3, To analyze bearing capacity and settlements of foundations.

4, To consider the relevance of site and ground investigation to soil and foundation engineering.
