应用有限单元法评价南社农业集中开采区的潜水资源,是“渭北黄土旱塬地下水资源评价及开发利用研究”课题中地下水资源评价方法研究项目之一。目的在于探索有限单元法解算数学模型,评价地下水资源的全过程、实践效果和应用条件,以便于推广使用;并结合当地在开发利用地下水中存在的问题,提出合理开发利用的意见。本文对此作一初步总结。一、水文地质模型和数学模型的选择(一)水文地质模型研究区面积16.18Km~2,地处黄土塬间石川河谷的中段,属于一、二、三级阶地。潜水含水层为全新统至中更新统上部冲积砂砾卵石和砂层,赋存有丰富的潜水。它主要受地下
The application of finite element method to evaluate the submarine resources in Nanshe Agricultural Concentrated Exploitation Area is one of the research projects on groundwater resources evaluation in the project of “Research on Evaluation and Exploitation of Groundwater Resources in Weibei Loess Plateau”. The purpose is to explore the finite element method to solve the mathematical model, to evaluate the whole process of groundwater resources, practical effects and application conditions in order to promote the use of; and combined with local problems in the development and utilization of groundwater, put forward the views of rational development and utilization. This article makes a preliminary summary of this. I. SELECTION OF HYDROGEOLOGICAL MODELS AND MATHEMATICAL MODELS (I) Hydrogeological model The study area is 16.18Km ~ 2 and is located in the middle of the Ishikawa Valley between the Loess Plateau, belonging to the first, second and third terraces. Diving aquifers are all over the Holocene to Middle Pleistocene alluvial gravel pebbles and sand layers, there is a wealth of diving. It is mainly underground
