湿陷性黄土地基作为一种特殊的地质现象，其性质是遇水湿陷。这一特性导致土体承载力大幅度丧失，可能导致地基破坏。桩基础是湿陷性黄土地区常用的基础形式。挤扩分支支盘桩是近年来发展起来的一种新型桩型，以前还没有在工程中应用过。本文在湿陷性黄土中进行了三根分支挤扩支盘桩的浸水试验。研究结果可供类似工程参考，并为工程实践中挤分支盘桩的设计提供理论参考。
As a special geological phenomenon, the character of collapsible loess foundation is collapsible when penetrated by water. This character leads to the soil losing load bearing capacity largely and may lead to foundation failure. Pile is a popular foundation used in collapsible loess. The squeezed branch and plate pile is a new type of pile developed in recent years and has not be used in a project before. In this paper three squeezed branch and plate piles are tested in collapsible loess after immersion processing. The results may be used for reference in similar construction project, and to provide theoretical references for designing of the squeezed branch and plate piles in engineering practice.
