摘　　要：粘土的强度主要是指其抗剪强度,它主要由两个指标:粘聚力和内摩擦角,通过室内直剪实验来研究含水量对上述两个指标的影响,同时运用最小二乘法的原理来拟合实验数据且求出函数表达式,并对含水量与粘土抗剪强度关系给出定量的分析。The strength of clay mainly refers to its shear strength, and it mainly consists of two indicators ： cohesion and friction. Through the direct shear test the paper studies the impact of moisture on these two factors and uses the principle of least square method to fit the experimental data and derives function expression, and makes a quantitative analysis for the relationship of moisture ratio and the shear strength of clay.

关 键 词：含水量 抗剪强度 最小二乘法分析 直剪实验数据
