This paper presents the solution of c-φ soil slope stability problem using the pseudo-dynamic method assuming the log-spiral failure mechanism. The vertical slice analysis methodology is introduced to analyze the stability of the slope under vertical and horizontal seismic loads. The adopted pseudo-dynamic method in the present analysis considers the effect of phase difference and primary and shear wave velocity which travel through the soil medium during an earthquake. Considering the limit equilibrium method, the moment equilibrium condition for each slice was established and a factor of safety of the slope is evaluated. Results are presented in a tabular and graphical form to understand the effect of different parameters of slope soil. Comparisons of the present analysis are highlighted with the existing solutions. A numerical solution is also done by PLAXIS 2D to compare the present study under earthquake loading conditions.

考虑对数螺旋破坏面的边坡地震分析及数值验证

本文提出了c - φ的解假定对数螺旋破坏机理的拟动力方法，利用土动力特性分析土坡稳定性。引入了垂直切片分析方法来分析边坡在垂直和水平地震荷载下的稳定性。在本分析中采用的拟动力方法考虑了地震期间穿过土壤介质的相位差以及初级和剪切波速度的影响。考虑极限平衡法，建立了各层的弯矩平衡条件，并评价了边坡的安全系数。结果以表格和图形形式呈现，以了解边坡土壤不同参数的影响。通过现有解决方案突出显示当前分析的比较结果。
