摘要
提出地下水资源调查与评价的目标、基础、主线、手段和核心5个方面的基本关系;水文地质调查设计书应提出拟建的概念模型;指明当前数值模拟的核心是"防止模拟失真,提高仿真性";强调对水文地质条件的正确分析和建立模型论证的重要性。要避免对水文地质条件、地下水流动基本特征未加精细分析就提出数学模型。水文地质模拟者不应单纯地追求"拟合",只有在合理概化水文地质模型和采用正确的仿真技术的基础上才有真正意义上的拟合。模型识别是对水文地质条件的再认识。指出沿井孔滤管的进水流量和水头如何分布及用什么方法预测是当前井孔 含水系统数值模拟最基本的问题之一。列举了其中常见的、容易导致模拟失真的若干模拟要素。
This paper has five basic relationships has been discussed in groundwater resource survey and evaluation, which are target, foundation, thread, measure and core. The design for groundwater resource survey should bring forward the conceptual model planned to establish. This paper has also pointed out that the key for current numerical modeling is to prevent model loss reality and to improve model accuracy and emphasized the importance of correct analyzing hydrogeological condition and verifying model. It must be avoided that just posing the mathematic model without careful analysis of groundwater flow. It's only on the basis of rational generalizing the hydrogeological model and using proper method that the simulation is actuallyvaluable. How to predict the flux and head along the filters of well is one of the most essential problems in the present numerical simulation of wellbore\|aquifer system. Some common and important elements which can easily result in model loss reality are listed.
