| 摘 要： | 以辽宁省平原区为研究背景,建立了典型区地下水系统数学模型。提出了可变的开采含水层等效渗透系数和平均给水度的水文地质参数模拟方法,对常规分区法进行了改进,并应用于建立的数学模型中,提高了模型精度。用修正有限元法对数学模型进行数值离散,利用Visual Basic软件编制计算程序,对地下水系统进行模拟,取得了较好的模拟结果。建立的模型为进一步研究辽宁省平原区地下水状况和可持续利用提供了条件,研究方法对同类地区的模型研究具有重要参考价值。

| Abstract: | Taking the plain area in Liaoning province as example,This paper establishes a mathematical model for groundwater system in typical area,presents a variable hydro-geological parameters simulation method about the equivalent permeability coefficient of aquifer and average specific yield,and shows an improvement about the routine zoning method,which is used in the constructed model to increase the precision of the model.We use the modified finite element method to numerically discrete to the model,and establish the calculation program by using Visual Basic.The simulation result is better for the groundwater1 The constructed model provides condition for the research of the sustainable utilization of groundwater in the plains in Liaoning province.This method provides significant reference for the model research on similar area. |
