May 15, 2019· At the linear stage, the vertical load increases quickly while the settlement accumulates at a much lower gradient. The deformation of the sand inside and outside the foundation is not obvious, and it is mainly caused by the extrusion of the soil particles. The resistance is mainly provided by the base bearing capacity and the skirt frictions.
