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 distribution of groundwater flow field is the key factor to evaluate the stability of landslide body. Visual MODFLOW groundwater numerical simulation software was used to establish three models of the Yichangping landslide under natural, heavy rain and drainage conditions. Improve the accuracy of the natural model through parameter inversion. The analysis of heavy rainfall and drainage shows that heavy rainfall raises the water table of landslide area and forms Yong high water level in some areas, while the underground drainage project of corridor reduces groundwater level, and the project has obvious effect.
