为了评估边坡破坏的风险，本研究采用了严格的方法，被称为随机有限差分法（RFDM）。RFDM能够考虑不同自相关结构下土壤性质的空间变异性。针对两个理想化斜坡与收集的数据进行比较，并进行参数分析。结果表明，空间自相关结构对边坡失稳风险有显著影响。根据旋转的角度，旋转的各向异性自相关结构的斜率的可靠性相比，横向各向异性的情况下，表现出双重效果。
To assess the risk of slope failure, this study employs a rigorous method that is referred to as the random finite difference method (RFDM). The RFDM is capable of considering the spatial variability of soil properties subject to different auto-correlation structures. Comparisons with the collected data are made with respect to two idealized slopes, and a parametric analysis is presented. The results demonstrate that the spatial auto-correlation structures significantly affect the slope failure risk. Depending on the rotated angle, the rotated anisotropy auto-correlation structure shows a dual effect on the reliability of the slope compared to a transverse anisotropy case.
