| 摘 要： | 分析了基坑降水引起坑周边地面沉降的机理、影响范围，探讨了基坑降水引起地面沉降的影响因素及减少地面沉降的措施。以“上海某钢铁公司1780mm热轧厂旋流池超深基坑的深井降水”工程为例，指出之所以出现周边环境安全问题，多因抽水中含砂量高引起。

| Abstract: | The article analyses the mechanism and affected range of surface settlement around by excavation perviousness, and discusses the affecting factors and the measures to control it.Taking the example of the deep well saturation project of cyclone tank, which has excessively deep excavation, in the 1 780mm Hot-Rolling Factory of an iron and steel company of Shanghai,the author considers the environmental safety problems are mainly caused by the high silt content in the process of pumping. |
