Advanced reliability analysis of road-slope stability in a brittle and faulted rockmass terrain by several techniques is described in this paper. The proposed analysis integrates several classical methods for the analysis of slope stability. The methods include remote sensing technique together with kinematic analysis, Finite Element Method (FEM), and Finite Difference Method (FDM). The Sentinel-2B imaging techniques have classified most of the slopes as high susceptibility, most of these slopes have been observed to consist of active rockfalls. Furthermore, circular, toppling, planar, and wedges failures were denoted to be the most kinematic failures associated with the slopes. However, wedge failure was more pronounced than other kinematic failures. On the other hand, simulation of FoS and maximum displacement of the slope was conducted using FLACSlope. The simulation confirmed that the composition of the slopes contributes greatly to its FoS and rockmass displacement. Indeed, a slope with one rock unit was simulated to be stable with less rockmass displacement, however in a case of brittle and faulted rockmass the FoS was very low with extensive displacement simulated across the slope. The later simulation corresponds with the conditions of the current study. Finally, the influence of geological features was studied with varying stages of road construction. The simulations have shown a rapid increase in rockmass displacement generated by the joints as the stages of road construction progress. It appears that the brittleness, faulting, slope properties, and unsupported rockmass are the most contributing factors toward slope instability.

本文介绍了通过几种技术对脆性和断层岩体地形中道路边坡稳定性进行的高级可靠性分析。所提出的分析方法综合了几种经典的边坡稳定性分析方法。这些方法包括遥感技术以及运动学分析，有限元方法（FEM）和有限差分法（FDM）。Sentinel-2B成像技术已将大多数坡度归类为高磁化率，已观察到这些坡度中的大多数都由活跃的岩石落组成。此外，圆形，倾斜，平面和楔形破坏被认为是与坡度相关的最运动学上的破坏。但是，楔形破坏比其他运动学破坏更为明显。另一方面，使用FLACSlope对FoS和最大位移进行了模拟。模拟结果表明，斜坡的组成对其FoS和岩体位移有很大贡献。的确，模拟一个岩石单元的斜坡是稳定的，岩体位移较小，但是，在脆性和断层岩体的情况下，FoS非常低，在整个斜坡上模拟了大位移。后面的模拟与当前研究的条件相对应。最后，研究了道路施工不同阶段地质特征的影响。模拟表明，随着道路建设的进展，节理产生的岩体位移迅速增加。看来脆性，断层，坡度特性，
