万家寨引黄工程大梁段砂黄土的工程特性研究

Engineering properties of sand-loess from the Daliang region along the Wanjiazhai water diversion project

以万家寨引黄工程大梁水库周边地区砂黄土为例,通过试验分析,阐述了库区砂黄土的物质组成、物化性质和力学特性,并通过不同状态下砂黄土的微观结构特征对比,探讨了砂黄土作为库坝土料的适宜性,同时对砂黄土斜坡和隧洞工程易出现的问题进行了分析。

Based on the test results of sand-loess around the Daliang Reservoir of the Wanjiazhai water diversion project, the Characteristics including composition, physico-chemical properties and mechanical properties are summarized. By comparison of the sand-loess microstructures under different states, the applicability of sand-loess as filling material to a reservoir dam, as well as the engineering problems associated with the sand-loess slopes and tunnels, is discussed.
