摘　　要：深厚覆盖工程地质特性研究是川西河流上水电站建设中一个普遍性问题,其中,覆盖层砂土液化问题是坝基覆盖工程地质特性研究的关键问题之一。本文依据试验成果并结合规范技术要求,采用多种方法对川西某水电站坝基下砂土层液化进行了判别,为坝基下砂土层是否处理提供了建议依据。The study of deep coverage engineering geological characteristics is a common problem in the construction of hydropower stations on the western Sichuan river, wherein coverage sand liquefaction problem is one of the key problems in the study of dam foundation coverage engineering geological characteristics. According to test results and combining with the specification technology requirements, the paper adopted a variety of ways to discriminate the sand liquefaction under the dam foundation of a hydropower station in westem sichuan.
