| 摘 要： | 推导了圆柱体试件和长（立）方体试件，分别在不同表面摩擦力和不同高宽（径）比下基于双剪屈服准则下抗压强度的理论计算公式，并与实验结果比较所得结果与实验结果甚为吻合。其理论计算与实验结果都说明，试件尺寸的不同与表面抹油与否对水泥土抗压强度均有一定的影响。其高宽（径）越大，其强度越低且越趋于一定值。试件上下表面不摸油其抗压强度略高抹油情况。

| Abstract: | A calculating formula of compression strength for cement-stabilized soil in different sample sizes ratio of height to width (or ratio of height to radius) and surface frictional forces has been derived by twin shear stress yield criterion. The calculation results with the formula are farely coincide with the experimental ones. It is showed that the sample sizes and surface frictional forces influence the compression strengths. The bigger ratio of height to width (or radius) of the sample is, the less is its compression strength. The compression strength of the cement-stabilized soil sample putted on oil is lower than the no oil putted on it. |
