摘要
南水北调北京市东干渠地下水循环动态类型分为渗入、蒸发、径流型和渗入、径流型两种,两者均接纳大气降水入渗、侧向径流补给。排水方式主要为地下水侧向径流和越流,总体流向自西北向东南。区内基岩裂隙水和松散类孔隙水的分布受构造的控制。应研究地下水循环规律,以减少地质变化对管线的危害。
There are two kinds of underground water circle dynamic types of Beijing City east main canal of South-to-North Water Diversion Project： penetration, evaporation, runoff type and penetration, runoff type. This two types all absorb atmosphere rainfall to support runoff. The dewatering modes are underwater cross runoff and overflow, the whole flow direction is from northwest to southeast. Distribution of bed rock crevice water and loosen pore water in this region are controlled by structure. The underwater circle law is researched to reduce the hazard of geology changes to pipelines.
