摘要

在暴雨和洪水期间，土坝溃坝和滑坡是世界各地普遍存在的问题。本文考察和讨论了降雨和洪水引起滑坡的原因。气候降雨数据与降雨及其对土坡孔隙水压力增加的影响相互关联。分析了不同几何形状和材料性质的土质边坡，计算了孔隙水压力和边坡安全系数的变化规律。在地震和非地震情况下，研究了地下水位(GWL)与边坡FS之间的相关性。剪切强度(τ)、剪切应力(σ)与FS之间也存在相关性。巴基斯坦的Kotkai滑坡被认为是一个案例研究，用于交叉检查已开发相关性的正确性。这些相关性可以应用于强洪水和强降雨地区的安全土坡设计。

Correlating groundwater level and shear strength: Kotkai Pakistan landslide as case study

Earth-fill dam failure and landsliding during heavy rainfall and flooding is a common problem observed all over the world. This paper examines and discusses the causes of landsliding due to rainfall and flooding. Climatic rainfall data are interconnected with rainfall precipitation and its effect on the increase in pore water pressure inside soil slopes. Various soil slopes with different geometries and material properties are analysed, and the variation in pore water pressure and the slope factors of safety (FSs) are calculated. Correlations between the groundwater level (GWL) and slope FS are developed in both seismic and non-seismic situations. Correlations between shear strength (τ), shear stress (σ) and FS are also developed. The Kotkai landslide in Pakistan is considered a case study for cross-checking the correctness of the developed correlations. These correlations can be applied to design a safe soil slope in intense flood and rainfall areas.
