含水层参数的确定,是进行地下水资源科学管理的基础和关键。针对含水层参数反演解往往不唯一的问题,提出采用最优化方法中的逐个修正法,将反问题转化为一系列的正问题进行求解;利用正问题的解是适定的这一性质,克服了反问题不适定问题;最后以无界承压含水层井流模型为例,讨论了逐个修正法在含水层参数反演中的应用,实例分析结果表明,此种方法有很好的稳定性,是一种值得在实际中推广应用的含水层参数反演方法。
The determination of aquifer parameters is the foundation and key to the scientific management of groundwater resources. Aiming at the problem that the inversion of aquifer parameter is not always the only one, a new correction method in the optimization method is proposed, which transforms the inverse problem into a series of positive problems to solve. Using the solution of the positive problem is a proper one, Finally, taking the unbundled confined aquifer flow model as an example, the application of the one-by-one correction method in the inversion of aquifer parameters is discussed. The example analysis shows that this method has good stability , Which is a kind of inversion method of aquifer parameters which is worth popularizing in practice.
