摘要
桩基础具有承载力高、沉降量小等特点,在工程建设中广泛应用.桩-土界面力学特性是影响桩基础承载力与沉降变形的关键因素.工程实践中非饱和土体广泛分布,桩基础的沉降预测与承载力预估往往与理论相差甚远,非饱和土与桩相互作用的理论研究滞后于工程实践.系统总结了桩-土界面相互作用、桩-土间荷载传递规律、复合地基固结理论等方面的研究现状,指出目前复合地基沉降变形中的桩-土相互作用研究中存在的主要问题,为相关研究提供参考.
Abstract
The pile foundation is widely used in the engineering construction because of its high axial capacity and the small set-tlement.The mechanical properties of the pile-soil interface are the key factors affecting the axial capacity and the settlement deformation of the pile foundation.In engineering practice,the unsaturated soil is widely distributed,and the settlement pre-diction and the axial capacity prediction of the pile foundation are often far from the theory.The theoretical research on the in-teraction between the unsaturated soil and the pile is far behind the engineering practice requirements.This paper summarizes the research on the mechanical properties and failure mechanism of the pile-soil interface,the pattern of the pile-soil load trans-fer and the consolidation theory of the soil around the pile foundation,to provide a reference for the relevant research.
