水泥土的室内试验研究
Laboratory Experimental Research on Cement Soil
【摘要】 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.研究结果为有效控制和检验水泥土搅拌法对软土地基的加固效果提供了依据
【Abstract】 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.
【Key words】 cement soil; compressive strength; porosity; density; acoustic velocity;
