摘要
本文根据有限元法,提出了一种模拟我国北方岩溶泉流行为的数值方法,用来处理在模拟泉流过程中所遇到的特殊问题。首先将泉流量以地下水位的线性形式表达出来,然后再把它表达成为自然排泄强度,加入到带有泉的地下水的数值模拟模型中去,通过求解带有泉的地下水系统的有限元模拟模型,就可以同时确定地下水位和泉流量。应用这种方法模拟济南岩溶泉水,结果令人满意。
This paper presents a numerical approach based on finite element method for the simulation of North China' s karst spring outflow behaviour. The approach is used to deal with the special problems encountered in the process of simulating spring outflow. At first, spring discharge is expressed in the linear form of groundwater level, and then in the form of natural discharge rate per unit area. This natural discharge rate per unit area is added to the simulation model of the groundwater system with springs. By solving the simulation model of finite element of the groundwater system with springs, the spring discharges together with groundwater levels can be obtained. The results show that the approach is feasible and satisfying.
