先挤密后灌注桩在深厚湿陷性黄土地区的应用

Applied Study on Compacted Pile Combining Caisson Pile in Dealing with Wet and Sink Loess

湿陷性黄土是西北地区常见的一种工程地质问题,本文结合工程实例,采用先挤密地基土,后施工混凝土灌注桩的方法处理湿陷性黄土,对大厚度湿陷性黄土进行岩土治理,并达到了良好的效果,为特殊条件下的岩土治理提供了解决问题的方法。

Damp-risk loess is a common engineering geological problem in northwest regions. In this paper,the method that compact the foundation soil first then constructs the caisson pile is used, the high thickness wet and sink loess were solved. Treated.good results were obtained from the treatment and could provide the solution to the rock and soil treatment under the special conditions.
