| 摘 要： | 介质概化是水文地质概念模型建立和进行地下水流三维数值模拟的基础。目前国内、外已建立的岩溶介质地下水流模型,都有一个共同的特点:在进行岩溶介质概化的时候,大都采用等效裂隙介质模型方法。由于岩溶介质的空间不连续性和各向异性,决定了采用该方法概化岩溶介质必然造成与实际情况不符。为了更加准确地概化岩溶含水介质,同时也为了使概化后的介质模型,能比较真实地刻画出实际岩溶介质的含水层,这里以广西合山煤田为例,针对岩溶含水介质的特征,以及岩溶发育规律,提出了对模拟区域采用多种方法进行介质概化,对不同类型的岩溶介质采用不同的方法进行概化处理,从而实现了对复杂岩溶介质的概化。

| Abstract: | The generalization of seepage medium is the foundation of hydro-geological model building and numerical simulation of groundwater.Making a general survey of the groundwater model which had already finished in the karst area in the world,we can find there is a common characteristic as that porous continuous medium model or equivalent cranny medium model or others are taken in generalizing the complex karst medium.because of the spatial discontinuity and anisotropism of the karst medium,only one kind of generalization method adopted to the karst medium will lead to unconformity with the real conditions.In order to generalize the karst medium more accurately in the process of groundwater field simulation and match the generalized simulation model with the real karst medium in aquifer of karst medium,the article adopts many ways to generalize the complicated karst medium and to deal with it. |
