摘　　要：复合地基作为一种提高软弱土地基承载力的有效手段,被广泛应用于工程建设中。褥垫层作为复合地基中的一个关键组成部分,其厚度的选取对地基性能有着重要影响。文中主要讨论复合地基褥垫层厚度的影响因素,分析了褥垫层的变形和受力机理,以及变形后对桩体产生的负摩阻力影响,外荷载作用下复合地基褥垫层厚度的对地基承载力的影响。Composite foundation,as an effective means to improve the bearing capacity of weak soil foundation,has been widely used in engineering 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.
