Explain the various geotechnical problem in soil mechanics.

The basic geotechnical problem associated with soil mechanics are:

• Problem of stability 
• Problem of elastic and plastic deformations 
• Problem due to failure of various structure like pavement, retaining structures, dams, foundations etc.

In case of stability, problem arises due to sudden collapse of resisting capacity of the soil. To prevent failure due to stability, the following questions need to be answered:

• What load is imposed on soil?
• What magnitude of stress does the load induce to the subsoil?
• How much resistance the soil can sustain?

Similarly, in the problem of deformation,the magnitude of elastic and plastic deformation and rate of deformation need to be assessed. The magnitude of deformation should be kept within a certain limit in which a structure can tolerate.

The various problems associated with pavement design, foundation failure etc are fatigue failure, frost, heave and thaw etc.<....
