摘　　要：文章利用GMS中的FEMWATER模块,根据研究区的工程地质与水文地质条件,建立了三维有限元数值模型。用FEMWATER在稳定流情况下对该模型进行了多种工况计算,分析了排水廊道对研究区三维渗流场的影响与各种工况下的渗流场状况,并计算了相应的排水廊道排水量。计算结果显示,FEMWATER对复杂水文地质条件下的三维有限元模型建立非常有效,计算的排水系统排水量远小于设计排水量,可以将排水廊道的设计尺寸适当调小。In this paper, a 3-D finite element model is built according to the hydrogeological and engineering geological conditions of the study area, using FEMWATER module of GMS （Groundwater Modeling System）. The FEMWATER module is used to compute the model in a steady state. The paper analyzes the impact of the drainage gallery on the seepage flow field and the state of the seepage flow field under different working conditions and the discharge from the gallery is also calculated. Conclusion can be drawn that the FEMWATER is effective for building models under complex hydrogeological conditions. The calculated result of the maximal drainage is much less than that of the designed discharge. As a result, the size of drainage gallery can be reduced aptly for the study area.
