摘要
地下水流场的分布是评价滑坡体稳定性的关键因素。使用Visual MODFLOW地下水数值模拟软件,建立窑厂坪滑坡在天然、暴雨和排水条件下的三个模型。通过参数反演提高天然模型的精度。分析暴雨和排水模型表明,强降雨抬升滑坡区地下水位,并在部分区域形成雍高水位,而廊道地下排水工程降低地下水水位,工程效果明显。
The groundwater flow field plays a key role in the landslide＇s stability evaluation. The simulation software of Visual MODFLOW is used to set up three models for the Yaoehangping landslide respectively under steady natural, rainstorm and drainage condition. The analysis of the simulation results shows that heavy rainfall raises the area＇s groundwater level and causes a high hydraulic gradient at some spots while drainage lowers the level, with obvious engineering effects.
