水泥土的室内试验研究

Laboratory Experimental Research on Cement Soil

为研究水泥搅拌法加固软土的特点和可靠适用性，进行了室内多因素水泥土的试块配比试验．试验结果表明：淤泥质粘土中掺入一定量的水泥搅拌后，土的物化性质得到改善；水泥在原土中的胶凝和骨架作用，加强了土颗粒间的联结性，降低了土的孔隙率和含水量，增大了土的密度，提高了土的抗压强度和抗拉、抗剪能力．

Based on laboratory tests of cement soil grading, the property of soft soil reinforced by use of the mixing method is revealed in this paper. The test results are:①The soil property will be improved when mixed with cement in mucky soil;②The cement plays a role of gelation and skeletal texture in undisturbed soil;③The connection between soil particles will be strengthened;④The moisture content and porosity will be reduced;⑤The compressive, tesile and shear strength will be improved.The results can be used for checking and controlling the effect of softsoil foundation improvement with cement mixing method.
