膨胀土渠道边坡处理技术

膨胀土、膨胀岩问题是南水北调中线工程的主要工程地质问题之一,由膨胀土、膨胀岩组成的渠坡容易出现渠道衬砌破坏和滑坡。从分析膨胀土滑坡产生的实质入手,提出浅层滑坡是膨胀土滑坡的主要形式,也是处理重点。介绍国内外膨胀土边坡工程处理方法,提出针对膨胀土渠道不同部位的工程处理技术。以期对中线工程膨胀土渠坡设计有所帮助。

The Treatment of Swelling Soil of the Canal Slope

The swelling soil/rock is one of the main engineering geological problems in the middle route project of the northward water transportation work.The canal slope with them is easy to suffer canal lining failure and landslide.After analyzing their reasons,the authors considered that the shallow landslide be the main damage and should be treated with most attention.The authors discussed the major methods to tackle this problem in the world.There exist different treatment at different parts of the canal slope,all of which may be of value in the construction the middle route project.
