摘要
通过一系列水泥土工程力学性能试验,得到了水泥土的基本力学参数.对试验结果进行回归分析后,给出了水泥土抗压强度的影响因素及其与抗压强度的关系、变形模量与抗压强度的关系、抗剪强度与正应力的关系、水泥土应力-应变曲线的回归方程以及不同水泥掺量和龄期的水泥土抗压强度推算公式.
A series of laboratory tests was carried out, and the basic mechanical parameters of soil-cement mixture were measured. By curvilinear regression of the data, relations between strength and its influencing factors, secant modulus and prismatic compressive strength, shear strength and normal stress were given. At the same time, regression equation of stress-strain curve of soil-cement mixtures and relational expression between cement content and age are suggested.
