考虑可控非可控因素动态特性的含水层系统有限元模拟模型

本文提出了考虑可控非可控因素动态特征的水资源系统有限元动态模拟模型，将各单元逐时段系统输入输出信息的动态计算模型引入到模型中，然后由于这些量的动态特性，加之需要模拟识别的参数繁多，给有限元模拟模型的求解工作增加了很大的难度，我们在分析各类参数及曲线精度及物理概念的基础上，先固定一部分参数和曲线，然后从剩余参数的物理概念出发，确定其初值及其相互间的逻辑关系，最后由有限元模拟模型识别出这些参数，通过验证表明了模拟参数的准确性，也充分说明了有限元各项项信息量确定的准确，系统输入输出信息量计算模型合理可靠。

FINITE ELEMENT SIMULATION MODEL OF AQUIFER SYSTEM WITH CONSIDERED DYNAMIC PROPERTY OF CONTROLLABLE AND UNCONTROLLABLE FACTORS

In this paper, finite element simulation model of aquifer system with considered dynamic property of controllable and uncontrollable factors is raised and put a computer model of system input and output at each element and time interval into the model. However because they are of dynamic property and there are many parameters need to be identified, the solution of finite element simulation model is very difficult. According to the analysis of various parameters and curve accuracy and their physical concept, a part of the parameters are first fixed. Then the initial value and inter relationship of the rest of the parameters are determined according to their physical concept. Finally these parameters are identified through the finite element simulation model. Verification has explained the accuracy of the determined and simulated parameters and determination of finite element information, and the reliability of calculation model of system input and output.
