摘要:
在传统的剪应力模型的基础上，提出了全新的剪应力本构模型，该模型可以很好地弥补传统剪应力模型的不足，能较好地对边坡渐进破坏的过程实施预测预报。在全新剪应力本构模型以及条分法的基础上，通过计算滑面的摩阻力和下滑力，从而得到剩余下滑力，当第i条块的剩余下滑力大于零，第i+1条块的剩余下滑力小于零，则临界条块必然位于第i+1条块内，为了使临界条块的位置更精准，可以对第i+1条块进行再次划分，以此让计算结果更精确。另外，本文采用CDM法计算该滑坡在下滑方向的稳定系数，当计算的第i条块的稳定系数大于1时，则滑坡处于稳定状态。通过研究分析表明，王家岭滑坡处于基本稳定状态。
Abstract:
 The traditional shear stress model has some limitations in analyzing slope stability. Based on the traditional shear stress model, this paper puts forward a new shear stress constitutive model, which can compensate for the shortcomings of the traditional shear stress model and predict the progressive failure process of slope. Based on the new shear stress constitutive model and slitting method, the residual sliding force is obtained by calculating the friction and sliding force of the sliding surface. When the residual sliding force of the i+1 block is greater than zero and the residual sliding force of the i + 1 block is less than zero, the critical block must be located in the i + 1 block. In order to make the position of the critical block more accurate, the i + 1 block can be redrawn. In addition, in order to make the calculation more accurate, CDM method is used to calculate the stability coefficient of the landslide in the sliding direction. When the stability coefficient of the i block is greater than 1, the landslide is in a stable state. According to the above analysis, Wangjialing landslide is basically stable.
