Analysis of Factors Influencing the Thickness of Composite Foundation Cushion Layer
Composite foundation,as an effective means to improve the bearing capacity of weak soil foundation,has been widely used in engi-neering construction.As a key component of composite foundation,the selection of mattress thickness has an important effect on foundation performance.This article discusses the influencing factors of the thickness of composite foundation cushion layer,analyzes the influence of the thickness of composite foundation cushion layer on the bearing capacity of the foundation under external loads through the deformation and force mechanism of the cushion layer,as well as the negative frictional resistance generated by the deformation on the pile body.
