南水北调中线工程总干渠考虑采用水泥土作为衬砌材料。对水泥土配合比的选择进行了室内试验，按照室内试验结果进行了现场工艺试验。试验表明，土料粘粒的含量为１０％～２０％，水泥掺量为８％～１２％，水泥土的无侧限抗压强度可以达到设计值４．９０ＭＰａ的要求。现场试验也表明，南水北调总干渠采用水泥土作衬砌材料完全可行。 The South-to-North Water Diversion Project main canal considering the use of cement soil as the lining material. The cement-soil mix ratio of the choice of an indoor test, in accordance with the results of the laboratory test site technology. The test shows that the clay content is 10% ~ 20% and the cement content is 8% ~ 12%. The unconfined compressive strength of cement soil can meet the design requirement of 4.90MPa. Field tests also show that it is perfectly feasible to use cement soil as the lining material for the main canal of the South-to-North Water Diversion Project.
