非稳定流抽水试验参数计算的迭代算法及计算机模拟

Iterative algorithm and imitation for Parameter calculation of non-equilibrium flow bumping test

本文将高斯－牛顿迭代算法用于分析非稳定流抽水试验数据，利用文中的方法可同时算出经多次选代运算后的最佳含水层导水系数Ｔ、储水系数ｕｅ和渗透系数Ｋ，与现有的方法相比，它具有如下特点：（１）计算出的参数是经过多次迭代后的最优值；（２）计算过程通过编制计算机程序由计算机自动完成，省时，高效；（３）文中的方法和稍加修改的程序还可用于稳定流抽水试验数据的分析及参数计算，从而拓宽了该方法的应用范围．

Gause-Newton Iterative algorithm was used for analysing non-equilibriumflow pumping test data in this article. Based on this method the best aquifercoefficient of transmissibility, coefficent of storage and coefficent of permeabilitycan be derived. The parameters calculated were optimized. Calculation can becompleted automatically, with time-saving and high efficiency.
