| 摘 要： | 南水北调中线工程膨胀土渠段长,处理技术难度高,制约因素多,通过在南阳膨胀土试验段对渠道破坏机理进行研究,分析了膨胀土产生滑坡的原因:土性差是内因,水文条件、施工工艺、渠坡荷载等是外因.为有效防治滑坡,应重视膨胀土膨胀性的确定,合理编制土方开挖计划,施工时避开雨季等.

| Abstract: | There are long expansive soil channels in the middle route of the South-to-North Water Diversion project.Dealing with the expansive soil has high technical of difficulty and lots of restrict factors.According to the study on the channels destroy mechanism of expansive soil in Nanyang area,the causes of landslide in expansive soil area are analyzed.Results suggest that the poor nature of the soil is internal cause,and the external causes are hydrological conditions,construction technology,the load on the cha... |
