南水北调中线工程地质综述

Engineering geological summarization of the middle route project of S-N water transfer

南水北调中线工程线路长,跨越长江、淮河、黄河、海河4大流域,工程地质条件差异较大。自20世纪50年代迄今,长江水利委员会及其它科研设计单位对中线工程全线及大型交叉建筑物进行了工程地质勘察,同时对特殊类土(膨胀土、黄土)、渠线过煤矿区、区域构造稳定性、砂土液化等专题进行了研究。对南水北调中线工程的工程地质条件已基本清楚,涉及的主要工程地质问题均可以通过一定的工程措施予以解决。

The middle route project of S-N water transfer is a long route one, crosses 4 basins of the Yangtze river,the Huihe river,the Yellow river,the Haihe river,and the engineering geologic conditions differ greatly.Since 1950s, Changjiang Water Resources Commission as well as other scientific research units have carried out engineering geological reconnaissance for large-scale cross structures and the whole route,meantime,researched special subjects,such as special soils(expansive soil,loess),the canal section in coal mining area,regional structure stability,sandy soil liquefaction etc.The engineering geological conditions of the middle route project of S-N water transfer have been known well and all the involved main engineering geological problems can be solved through engineering measures.
