一、概述地面沉降是一个复杂的水文地质和工程地质问题,其诱发因素多种多样,导致上海区域性、大面积地面沉降的主导因素是抽吸松散层含水介质中的地下水。水位是河流或其它水体的自由水面相对于某一基面的高程,它是水利建设、防汛抗旱的重要依据。同时,水位也是为河道、航运、城
I. Overview Ground subsidence is a complex hydrogeology and engineering geology problem with many kinds of inducing factors. The leading factor leading to the regional and large-scale land subsidence in Shanghai is the pumping of groundwater in loose-layer aquifer medium. Water level is the elevation of a free surface of a river or other body of water relative to a certain base surface. It is an important basis for water conservancy construction and flood control and drought relief. At the same time, the water level is also for the river, shipping, city
