摘　　要：为增强边坡临界滑动场软件的适用性,考虑孔隙水压力及外水压力,在软件中增加水压力模块,使其适用于临水岸坡的稳定性分析。为验证软件的实用性,将其应用于三峡库区某动水压力型滑坡的稳定性评价,并与GeoStudio软件的计算结果、GEO-SLOPE软件的搜索结果进行比较。结果表明,增加水压力模块后的软件适用于水位变化过程中的岸坡稳定性分析,能够较好地自动搜索出地层复杂的滑坡临界滑动面,拓展边坡临界滑动场软件的工程应用范围。Considering the pore water pressure and external water pressure,the software for computing critical slip fields is improved by adding water pressure module.In order to verify the practicability of the improved software,it is applied to the stability evaluation of a landslide in the Three Gorges Reservoir area and compared with the calculation results of GeoStudio software and the searching results of GEO-SLOPE software.The analysis of examples show that the improved software is suitable for the analysis of hydrodynamic pressure landslide,and can automatically search out the critical slip fields of landslides with complex geological conditions,which expands the engineering application range of improved software for computing critical slip fields.
