一、导言沿不同方向有不同透水性的介质,叫做各向异透水性介质,简称各向异性介质。在这种介质中的地下水运动规律,还没有很好地研究过。但在大自然里,却经常碰到这种介质。裂隙岩石,不管它的裂隙是在构造运动还是在风化作用中形成的,其裂隙的发育往往顺着几个固定的方向。沿着这些方向的透水性, I. INTRODUCTION Media with different water permeability along different directions are called anisotropic water-based media, referred to as anisotropic media for short. The law of groundwater movement in this medium has not been well studied. But in nature, but often encountered this medium. Fractured rock, whether its fractures are formed during tectonic movement or weathering, the development of fractures often follows several fixed directions. Permeability along these directions,
