| 摘 要： | 单纯形与罚函数相结合的SWIFT方法应用于水文地质计算,可反求具有界限约束的水文地质参数。通过实例计算,找到了一个较好的初始单纯形的步长乘子V和单纯形缩小因子rv,从而减少目标函数的计算次数,节省机时。

| Abstract: | The SWIFT method combining the simplex with the sequential unconstrained minimization technique ( SUMT ) can be applied to the hydrogeol-ogical calculation and the inverse evaluation of the hydrogeological parameters. Although the method may avoid some abnormal phenomena such as the specific yield (p.) greater than 1 or the hydraulic conductivity ( K ) less than zero, more computing time will be spent than using the simplex technique if the step-factor V of an initial simplex and the shrink-factor rv of the simplex are unappropriate. The better V and rv was found by an example in this paper. |
