摘要
土的含水量和压实度是影响膨胀土抗剪强度的重要因素。在实验室研究了不同含水量和压实度情况下土的抗剪强度特性,采用多元线性回归方法,分析了内摩擦角和粘聚力与含水量和峰值抗剪强度的关系,发现重塑膨胀土的抗剪强度参数与压实度无显著相关,含水量对其有显著影响,定性分析了不同含水量下土的剪应力与位移的关系。
water content and compaction of soils have great effect on their shear strength. Considering the two variables, laboratory study is put forward. Through multiple linear regression, the relationship between the two factors and shear strength is studied, and a conclusion that compaction has little effect on shear strength with great water content in soils, and water content is major factor, is drawn, preliminary study on the relationship between shear stress and and displacement is also given.
