简单介绍了level set方法的基本原理,并将其应用到含水层参数识别问题。将含水层中两种介质的界面看作level set函数的零水平集。首先给定一个初始界面,然后根据观测水头与计算水头之差,使lcvel set函数以一定方式运动,从而使计算出来的界面逐步逼近真实界面。文中给出了两个数值算例,结果表明该方法可以有效地处理含水层参数识别问题。 The basic principle of level set method is briefly introduced and applied to aquifer parameter identification. Think of the interface between the two media in the aquifer as a zero level set of the level set function. First, given an initial interface, and then according to the difference between the observed head and the calculated head, lcvel set function to a certain movement, so that the calculated interface gradually approximation of the real interface. Two numerical examples are given in the paper. The results show that this method can effectively deal with the aquifer parameter identification problem.
