灰土夯扩桩在湿陷性黄土地基中的应用分析

Application and Instance Analysis of the Rammed-expanded Lime Soil Piles in the Wet,Collapsible Loess Foundation

结合工程实例,介绍了灰土夯扩桩在高层住宅楼湿陷性黄土地基处理中的应用。从地基的湿陷性消除、复合地基的承载力等方面进行了试验与分析,认为在大厚度湿陷性黄土地基上的高层建筑,采用灰土夯扩桩处理地基经济可行。

Based on the engineering practice, in this paper, the application of the lime - soil rammed piles in the high -rise residential buildings is introduced. By testing and analyzing the removal of the collapsibility and the bearing capacity of the composite foundation, it is thought that on the very thick wet -collapsible loess foundation, adopting the lime -soil tamping piles to build the high- rises is economical and feasible.
