摘要
三峡工程坝区为前震旦系结晶花岗岩，受风化和结构面网络的制约，形成了不同类型的水文地质结构体，各类水文地质结构体在分布、埋藏、和渗透性等方面都各有其不同的特点，总体上构成了层状透水性和结构面网络透水性的双重透水特征。
Under the Influence of the weathering effect and restricted by the structural network, the Pre -sinian crystalline granite within the areas of the Three Gorges Project has formed diversified types of hydro-geologic structures that have various distribution, depth, and permeability including stratified perviousness and network perviusness of the structural plane.
