北京地铁七号线工程对城市区域地下水水位的影响浅析

Beijing's Subway Line(No.7) Project on the Ground water Level of City Area

北京地铁七号线工程将对改善城市交通环境、促进城市空间结构规划战略转移具有重要的作用和地位。本文在概述北京地铁七号线工程基本情况及沿线水文地质情况基础上,分析了地铁工程建设对地下水水位壅高的影响,采用推荐模式预测计算工程疏干降水影响范围。结果表明,北京地铁七号线工程建设过程中将不可避免的对地下水水位造成一定的负面影响,并相应提出了保护地下水水位的几点对策与建议。

Beijing’s subwayline(No.7)project will have an important effect and status on the improvement of urban traffic environment and the promotion of urban spatial stucture’s planning strategy migration.The base situation of Beijing’s subway line(No.7)project and geohy drologic condition along the line are mainly presented in this paper.Then it analyses the influences of banked-upgroud water level,simultaneous adopts recommended mode to calculate the influence areaof exhaustible pumping groudwater.There sultindicate that,Beijing’s subwayline(No.7) project will make a bad effect to groudwater level inevitably.At the end of the paper,in order to protect the groudwater level,some counter measures and suggestions are provided correspondingly.
