| 摘 要： | 大区域(大尺度空间范围上的)地下水系统通常由不同的地貌单元组成,水文地质条件复杂,建立地下水流模型的目的和要求、水文地质结构、流场、参数分区、各种补排项概化和处理方面与小区域模型有较大的差异,因此建模的准则也不同.FEFLOW对含水层分层、单元剖分、离散点插值、数据转换、边界条件赋值、河流边界、含水层均衡项等处理的特点,提高了建立地下水流模型的效率,使它更加适宜于建立大区域地下水流模拟模型.

| Abstract: | The groundwater system in large-scale areas generally consists of different geomorphologic units and complicated hydro-geological conditions, therefore it is quite different from the water system in small-scale areas in terms of the objectives and requirements of modeling, hydrogeological structure, flow fields, parameter layout and computation of various recharge and discharge. As a result, the rules of modeling for these two situations are also different. Because it is capable of handling the partition of aquifers, generation of meshes, interpolation of discrete nodes, conversion of data, computation of regional balancing and assigning of boundary conditions and it can greatly improve the work efficiency, FEFLOW is proved to be more suitable to build groundwater model for large-scale areas. |
