| 基于泰勒稳定数方法的拟静力分析是土坡地震稳定分析方法之一，该方法可以考虑水平地震作用得出地震作用下土坡的安全系数，但忽略了竖向地震作用的影响。为同时考虑水平和竖向地震作用，在前人工作的基础上，通过理论分析和公式推导，本文建立了一个能够同时考虑水平地震作用和竖向地震作用的解析公式，形成了改进的泰勒稳定图方法和计算流程。本文采用一个简单算例，通过与有限元计算结果的对比，验证了改进边坡稳定图方法的有效性。该方法能够方便地估算简单均质黏性土坡的稳定安全系数，为边坡工程抗震设计验算提供了参考。 |

| The quasi-static analysis based on the taylor stability number method is one of the methods to analyze the seismic stability of soil slope. This method can consider the horizontal seismic action to get the safety factor of soil slope under the seismic action, but ignore the effect of vertical seismic action. In order to consider the horizontal and vertical seismic actions at the same time, on the basis of previous work, through theoretical analysis and formula derivation, this paper establishes an analytical formula that can consider the horizontal and vertical seismic actions at the same time, and forms an improved taylor stability diagram method and calculation flow. A simple example is used to verify the effectiveness of the improved slope stability diagram method by comparing with the results of finite element calculation. This method can easily estimate the stability safety factor of simple homogeneous cohesive soil slope and provide reference for the seismic design and checking calculation of slope engineering. |
