WebGeotechnical engineering, also known as geotechnics, is the branch of civil engineering concerned with the engineering behavior of earth materials.It uses the principles of soil mechanics and rock mechanics for … WebThe Boussinesq equation is used to determine stresses at any given point at a certain depth due to surface point load. The magnitude of vertical stress σ V at a random point Q at a depth of H from the earth's surface, due to a point load P acting at point O, is given by the Boussinesq equation, which is. σ V = 3 P 2 πH 2 1 1 + r H 2 5 2.
WebSoil Consolidation refers to the process in which the volume of a saturated (partially or fully) soil decreases due to an applied stress.
