合肥地区上更新统黏土中桩土共同作用特征测试分析

TEST AND ANALYSIS OF THE PILE-SOIL COMBINED ACTION IN THE UPPER PLEISTOCENE CLAY IN THE HEFEI AREA

通过在合肥市某复合桩基工程中进行桩基及地基土受力测试分析,探讨了合肥地区上更新统硬塑—坚硬状态黏土中桩土应力分担比例、桩土应力发展趋势、桩土共同作用特征,为今后合肥地区在上更新统黏土中复合桩基设计积累了经验。

Through stress test of pile foundation and foundation soil in a composite pile foundation project in Hefei City,this paper discusses the stress sharing proportion of pile and soil,the development trend of pile and soil stress,and the combined action characteristics of pile and soil in the upper Pleistocene hard plastic to hard clay in the Hefei area,thus accumulating experience for further design of composite pile foundation in this kind of clay in the area.
