| 摘 要： | 应用非饱和土土力学的基本原理，在将膨胀土边坡抗剪强度考虑为分布变化场的情况下，对一实际膨胀土边坡进行了稳定性分析。从中找出滑面圆心位置与安全系数k的分布规律，验证了膨胀土边坡破坏的浅层性，进而总结出破坏规律，给出所分析边坡的合理坡率。

| Abstract: | According to the basic principle of soil mechanics for unsaturated soil,the stability of an actual expansive soils slope was analyzed with the shear strength considered as the variable with the deepness. The relationship between the center of slip surface and the safety factor k was obtained. The shallow character of the slip of expansive soils slope was validated. The failure rules were found and the reasonable gradient of the analyzed slope was put forward. |
