Approximate Analytical Method of Load-Settlement Relation for Composite Foundation under Embankment Load
Considering reinforcement zone and natural foundation as a whole, the displacement component formulas satisfy with the displacement boundary conditions were constructed based on some hypotheses. Considering friction influence under foundation, a approximate analytical algorithm of foundation deformation was established under embankment loads by the variational method of displacement, and the approximate analytical formula on the relationship between the load and the average settlement was derived. The static load model tests were carried out in laboratory to verify the feasibility of this method proposed in this paper.
