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 settlement. 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 prediction and the axial capacity prediction of the pile foundation are often far from the theory. The theoretical research on the interaction 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 transfer and the consolidation theory of the soil around the pile foundation, to provide a reference for the relevant research.

Key words: Pile Foundation engineering, Unsaturated Soils, Pile-Soil Interaction, Load Transfer, Composite Foundation Consolidation
