膨胀岩（土）渠道边坡施工技术探讨

摘要

A lot of advanced engineering technologies were applied in expansive soil ( rock) projects due to the scarcity of land resources. Taking a canal slope of Middle Route Project of South to North Water Diversion in Xinxiang County of Henan Province as example, the application of 3 measures, including geogrid, composite geo-membrane and modified cement soil, in the slope treatment were introduced. Through analysis of in-situ test results, satisfied effects were gained in expansive soil ( rock) slope treatment by the 3 measures.%针对我国土地资源紧张的现状，大量先进的工程技术逐步应用于膨胀岩(土)项目，以保证工程建设尽量少占用土地资源。结合南水北调中线工程河南新乡某渠坡试验段实际情况，重点介绍了土工格栅、复合土工膜、水泥改性土3种处理措施在膨胀岩(土)边坡处理中的应用。现场试验的结果表明，这3种处理措施在膨胀岩(土)边坡的处理中取得了良好的效果，其经验可供类似的工程借鉴。
