【摘要】 华北平原是世界上超采地下水最严重的地区,也是地面沉降面积最大的地区。大约有7万km~2的地下水水位低于海平面。随着近20年来的经济快速发展,城市化进程的加快,地表水污染程度的增加,高层建筑的施工以及对地下水的需求与日俱增,华北平原地面沉降呈现加剧的趋势。本文对华北平原地面沉降调查与监测提出了一整套的工作思路。更多还原

【Abstract】 The North China Plain has witnessed the most excessive pumping of groundwater in the world and covers the largest subsidence area with the most funnels on the planet The groundwater level of approximately 70000 km~2 kilometers in this region falls below sea level.Surface subsidence has picked up speed over the last two decades as a result of an increasing demand for groundwater caused by fast economic growth and urbanization,pollution of surface water and the construction of skyscrapers.This paper put forward a series of work programming to monitor and control land subsidence mainly caused by groundwater overdraft in North China Plain.更多还原
