| 摘 要： | 地面沉降导致上海地面高程损失,并降低防汛工程设防能力。1921~2007年地面平均沉降1.973 m,最大沉降3.035 m,市区普遍低于江河高潮位。地面沉降在中心城区外滩黄浦江防汛墙四次加高改建中分别占增高幅度的98.0%,62.6%,30.1%,7.8%,目前防汛墙仍受到地面沉降的持续影响,1994~2006年区域地面沉降占防汛墙总体沉降量的71.9%。地面沉降的长期危害是影响上海城市防汛安全的重要因素,加强地面沉降监测与防治是上海城市灾害防御的重要内容。

| Abstract: | The land subsidence directly threatens the safety of urban flood defence by decreasing the land altitude loss.According to the monitoring results of the land subsidence and the yearly highest tide height of the Huangpu River and all previous heightening and subsidence conditions of the flood defence wall in the Bund,it is shown that the amount of land subsidence in Shanghai was 1.973 m from 1921 to 2007 and the land altitude of center town is about 3.5m at present,and the land altitude of center town almost... |
