基于随机建模技术的水文地质岩相的模拟初探

Variability of hydrogeological parameters in soil pore space will badly affect flow of ground water and transportation of contaminant for small-scale hydrogeological models such as contaminant transport model. However, it is difficult to get such information needed by these models. Therefore, evaluating the spatial distribution of value of hydrogeological parameters for contaminant transport modeling in a proper way is quite critical. Simulated annealing and SGSM are used respectively in this article to build small-scale hydrogeological model. The simulating effect is compared with borehole data and study is carried out to find their affects to model building, which shows a new way for studying small-scale hydrogeological model.
