基于 Visual Modflow 的腾龙台地地下水数值模拟研究

摘要

Visual Modflow是综合Modflow、Modpath、MT3D、RT3D和WIN PEST等地下水模型而开发的可视化地下水模拟软件。新疆若羌县腾龙台地在充分研究该区区域地质、水文地质的情况下，使用Visual Mod－f low在该地区进行了地下水资源的模拟与预报，建立全区的水文地质数值模型（三维流数值模拟模型），发现强隐式法（SIP）求解方法精确度最高。按照设计开采量对地下水资源水位进行预报，根据模型预报结果设计开采量是可行的。实际应用表明Visual Modflow在地下水资源的评价中具有很高的应用和推广价值。%Visual Modflow is a visual software of groundwater simulation developed on the basis of Modflow ,Modpath , MT3D ,RT3D and WIN PEST ,etc .The simulation and prediction of groundwater resources in Tenglong mesa ,Ruoqiang , Xinjiang was carried out by using Visual Modflow ,after the thorough investigation of the regional and hydrological geology of the area .A hydrogeological numerical model (three-dimensional numerical simulation model ) of the whole area was es-tablished ,and it was found that the SIP method arrived at the highest accuracy .Based on the model ,groundwater level was predicted in the simulation according to the design production volume ,with the result showing that the design produc-tion was feasible .This result suggests that Visual Modflow has a good application and promotion prospect in evaluating the underground water resources .
