用Iverson解析解描述降雨入渗,并采用Moh-Coulomb强度准则,对降雨过程中平移模式下无限均质边坡的水平位移进行弹塑性计算,据此分析边坡安全系数和滑坡前坡面水平位移的关系,并探讨土坡的抗剪强度参数、降雨强度和初始应力状态对边坡安全系数和水平位移的影响.结果表明,对于抗剪强度参数较小的无限边坡,在较大的降雨强度作用时,滑坡很快就会发生,且滑坡前的水平位移较小,但初始应力状态对滑坡发生的时间没有影响.

The Iverson analytical solution was used to describe rainfall infiltration, and the Moh-Coulomb intensity criterion was used to calculate the horizontal displacement of the infinitely homogeneous slope under the translation mode during rainfall, according to which the relationship between the slope safety factor and the horizontal displacement of the slope before landslide was analyzed, and the influence of the shear strength parameters, rainfall intensity and initial stress state of the soil slope on the slope safety factor and horizontal displacement were discussed. The results show that for the infinite slope with small shear strength parameters, the landslide will occur quickly when the rainfall intensity is large, and the horizontal displacement before the landslide is small, but the initial stress state has no effect on the occurrence time of the landslide.
