应用微机分析含水层参数的通用最佳拟合法

GENERAL OPTIMUM FITTING FOR ANALYSING AQUIFER PARAMETERS ON MICROCOMPUTER

采用常规方法分析含水层参数,仅能解决单孔一阶梯问题。本文提出了通用最佳拟合法并在VICTOR—9000微机上通过。该法可解决多孔多阶梯问题。无论承压或无压、抽水或注水,凡是能通过映射变为无限问题的一切边界问题均可使用。 该法通过双向使用黄金分割法选优,能自动拟合出最佳参数,并能给出判断参数准确程度的标准。 该法可打印出原始数据、拟合水位、计算结果,并绘制和拷贝相应的匹配图形。 文后并附有实例及BASIC源程序。

Conventional method applied to analysing parameters of an aquifer can only solve the single hole - staircase probblem. In the paper, a general or universal optimum fitting technique is put forward- It is proved acceptable on , the microcomputer VICTOR - 9000, and can solve multihole-multistal cast problems. No matter whether the aquifer is confined or unconfined, being pumped or recharged, the technique is applicable to all kinds of boundary problems,only when the problems are converted into infinite through mapping. The automatic fitting by means of this technique may give optimum parameters through bilateral use of. the golden section method.A. criterion is thus obtained for judging the accuracy of the parameters. By using this method, the raw data and fitting level and calculation results can be printed out, and the corresponding matching maps can be mapped and copied. The example and BASIC source program are attached at the end of the paper.
