摘　　要：FEMWATER是GMS(Groundwater Modeling System)中的重要模块,是国际常用的模拟地下水流和溶质运移的模块,本文旨在对FEMWATER进行简单介绍,并详细讨论在GMS界面下,FEMWATER模块中三维有限元网格构建的各种技巧,以期对使用FEMWATER的同行提供借鉴,提高其建模的效率。最后用一个理想的算例说明在FEMWATER中对断层的处理。计算结果表明FEMWATER可以很方便地对隔水和导水断层进行模拟。The FEMWATER is one of the most important modules in GMS （Groundwater Modeling System）. It has been widely used to simulate the flow of groundwater and the solute transport in subsurface porous media. The software FEMWATER is briefly introduced and the different teehniqu~ for the grid construction are deeply discussed under the GMS interface, whichcould provide some useful information to enhance the efficiency of modeling when the FEMWATER is used. An ideal example is given to illustrate the modeling in the FEMWATER for faults, and the results show that the FEMWATER could simulate both the water conductive faults and the water proof faults conveniently.
