基于抽水试验的水文地质参数三维进化反演

Pumping test based 3D evolution inverse analysis for identification of hydrogeological parameters

提出求解水文地质参数的遗传反演算法,并将该方法应用于玄武湖隧道工程抽水试验中.结果表明,用遗传算法反演水文地质参数是可行的.这种方法的优点在于只须给出参数的取值范围,就可自动地搜索出最优参数值.

A method for inverse analysis of hydrogeological parameters based on the genetic algorithm is developed and applied to the pumping test for the Xuanwuhu Tunnel Project. The results show that the method is feasible for inverse analysis of hydrogeological parameters. The merit of the method lies in that only with a range of a parameter, the optimum value of the parameter can be automatically searched out.
