青岛市官路水库分散性粘土工程特性及改性试验研究

根据拟建的青岛官路水库筑坝土料常规土工试验、碎屑试验、双比重计试验、针孔试验、石灰掺量改性试验等研究成果 ,结合现场调查取得以下主要结论 :(1)青岛官路水库筑坝土料为分散性土 ,筑坝时必须采取处理措施 ;(2 )在官路水库分散性土料中掺加石灰可把它改性为非分散性土 ,石灰掺量以 1.0 %～ 1.5 %为宜

Behavior of dispersive clay and its limestabilized test in Guanlu reservoir in Qingdao

This paper is based on the result of the test of the dispersive clay of Guanlu reservoir in Qingdao. By means of the normal physical tests, disintegrative test, twohydrometer test, pinhole test, limestabilized test and together with the field investigation,the following primary conclusions were obtained:(1) Because most soil in Guanlu reservoir is dispersive clay, it is indispensable to take treatment measures; (2)By mixing lime in dispersive clay, it might be transformed into nondispersive clay.1.0%1.5% by weight would be the optimum quantity of lime.
