土壤的剪力强度为边坡稳定分析中最难掌握的因素之一,对于已确认滑动面之破坏边坡而言,若能以逆算分析法求取其剪力强度参数,将能更经济、有效地提供作为维护防治计划所需之资料。逆算分析法系假设边坡于破坏时之安全系数为 1,如此可得数组凝聚力 c值与内摩擦角φ值的组合,再依经验判断选取其中一组为设计用参数。以明潭水库地滑地之滑动破坏边坡为例,计算得其剪力强度参数为凝聚力 c =0.95t/m2,内摩擦角φ =2 5°。并与前人的研究试验结果比较相当合理,且能适切地诠释滑动边坡受地下水位变动的影响程度。故于缺乏实测参数的地区在进行边坡稳定或工程施设分析时,以逆算分析法计算应有相当之可信度。

Soil shear strength are the most difficult controlled factors on slope stability analysis.If we obtain this shear strength parameters by using back stability analysis method,that will provide more economical and effective data for conservation engineering plan in the slope failure case of given slide surface.Back stability analysis method assume the factorofsafety is 1 when the slope fall,as above,there are many combining values of cohensioncand angle of fric-tion φ,thus we can base on the experience judgement to select one of this design parameters. This research select Min-Tan landslide area as the example site,calculating result of the shear strengih parameters are c =0.95t/m2 and φ =2 5°,moreover comparing with previous experimental data can obtain reasonable results and suitable explanation aboutthe groundwater variation influence on slope stability.
