摘　　要：南水北调中线工程为国家战略性跨流域调水工程,北京段总干渠是该工程的末端部分,全长80.3km,采用管涵输水。由于渠道埋设于地下,路线漫长,且走向与区域地下水流向基本直交,局部地段可能会对地下水流动产生阻隔作用,进而带来次生影响。对北京段干渠的地下水影响问题进行了调查和分析,并提出了保护措施,对工程的环境保护具有重要的参考价值。As an interbasin water transfer project,the Beijing Section of the Middle Route Project of the South-to-North Water Transfer aims at alleviating the tense situation of water supply in Beijing. Sealed pipe cutvert will be adopted for this section, with the length of 80. 3 kin. Since groundwater flow of the region runs from northwest to southeast,being orthogonal with the pipe line,construction of the long underground pipe may obstruct of groundwater flow and then secondary environmental impacts. This paper studies the potential environment impacts on groundwater of the Beijing Section,and puts forward the countermeasures accordingly, It will provide the significant reference value to the environmental protection of the related projects.
