换填黏性土料工程特性试验研究OA北大核心CSCDCSTPCD
Experimental study of engineering property of replaced-backfilling clay
南水北调中线一期工程总干渠膨胀岩(土)试验段工程潞王坟段的渠坡处理方式之一是换填黏性土料处理措施,通过开展物理性试验、击实试验、膨胀特性试验和原位测试等来了解换填黏性土料的工程特性.研究表明:(1)换填黏性土料颗粒组成差异较大,以砂粒和粉粒为主,其次为砾,黏粒和胶粒成分较少,其级配一般;(2)轻型击实条件下,换填黏性土料最优含水率为17.7 %,对应的最大干密度为1.71 g/cm~3;重型击实条件下,换填黏性土料最优含水率为18.4 %,对应的…查看全部>>
One of the slope treatment measures is the replaced-backfilling clay treatment in the Luwangfen test region of middle-route of South-to-North water division project. The engineering property of replaced-backfilling clay is studied by physical test, compaction test, expansive property test and in-situ test. Studies show that: (1)the diversity of particle component of it is obvious, in which sand grain and silt are dominant, gravel is lesser, cosmid and colloi…查看全部>>
