| 摘 要： | 抽水试验最优化设计,是指针对一个具体的地下水系统优选出一个抽水试验设计,它使抽水试验的费用最小化,而试验所获资料能满足识别参数所要求的可靠性,它可以概化为一个非线性的混合整数规划问题,其决策变量是确定抽水井和观测井的位置及井数、抽水量和观测频率等,采用搜索算法求解了这一优化问题,得到了理论最优解,并进行了实例演算。

| Abstract: | In view of groundwater system, pumping test optimal design is to identify a least cost pumping thest design whose data will yield parameter estimaties of required reliablity. It can be generalized to a nonlinear, mixed integer programming problem. The decision variables are the location of the pumping and observation well, the pumping rate, and the frequency of observations. The optimal rate results of a hypothetical model have been solved by heuristic algorithm, and the algorithm has been verisfied by a case study. |
