Abstract

Abstract

The behavior of the composite ground under a flexible foundation is a complicated problem,which includes the interaction and stress-strain coupling among the flexible foundation,the cushion,the composite ground and the underlying strata.The law of load transfer of composite ground under a flexible foundation is analyzed firstly.And then a simplified analytic model is presented,in which the flexible foundation-cushion-composite ground-underlying strata is considered as an interactive system.According to the compatibility of stress and deformation on the interfaces between these four components,and considering the relative movement between the pile and the soil,the formulas of settlement and stress ratio of pile to soil,which are used to characterize the behavior of the composite ground,are derived.Finally,the rationality and applicability of the analytic solution are proved by one engineering case.
- composite ground,
- flexible foundation,
- interaction,
- analytic solution
