本文以天津市大港区某取水项目为例,介绍开采地下水的地面沉降影响评价方法和结果,并分析项目区域的可用水源条件,从地面沉降角度出发,建议该项目优先选用外部地表水源,不宜开采地下水。
Taking a water intake project in Dagang District of Tianjin as an example, this paper introduces the methods and results of ground subsidence evaluation of groundwater exploitation and analyzes the available water sources conditions in the project area. From the perspective of land subsidence, this project suggests that external surface water sources should be preferentially chosen and should not be mined groundwater.
