地下水位变化对水环境和水工建筑物影响较大。地下水位上升，会造成土地的盐碱化、沼泽化和浸没，使建筑物受到渗漏、浸泡和盐碱侵蚀的危害。在建中的建筑物，因地下水位上升而引起浮动、位移等不良后果。冬季还会造成建筑物冻害。地下水位下降会造成泉水枯竭、水质恶化、地面 Changes in groundwater level on the water environment and hydraulic structures greater impact. As groundwater level rises, it can cause salinization, swamping and submergence of the land, exposing the building to hazards such as seepage, soaking and salinization. Buildings under construction, due to rising groundwater levels caused by floating, displacement and other adverse consequences. Winter will also cause building frost damage. Decreasing groundwater level can cause depletion of spring water, deterioration of water quality and ground level
