黄土沟壑区湿软地基砾石桩处理应用研究

The application study on gravel pile composite foundation to the treatment of soft ground in loess ravine regions

结合黄陵—延安高速公路实践,介绍了砾石桩复合地基加固黄土沟壑区湿软地基的一般设计参数、适宜的施工工艺以及检测方法,得出了这种方法对黄土沟壑区湿软地基加固效果明显,是一种适宜的加固方法。

In this paper, the treatment technology of gravel pile composite foundation to soft ground in loess ravine regions was introduced on the basis of the practice of Huangling-Yan＇ an expressway, including its general parameter of reinforcement, suitable construction technics and quality test methods. Both the trial and practice results showed that this kind of treatment technology had good effect on the soft ground in this area.
