| 中文摘要:对地基沉降、位移极为敏感的邻近地铁隧道地区施工基坑降水工程时，为控制承压水采取回灌措施，既要克服基坑底板由于承压水造成基坑突涌等危害，又要减少基坑降水施工时对周边建（构）筑物造成的危害。通过邻近地铁2、4和9号线的上海盛大深基坑降水回灌工程成功实例，探讨邻近多条地铁区间隧道的超深基坑降水技术。 |

| Abstract:In dewatering near multiple subway tunnels sensitive to ground subsidence and displacement, recharge measures are often taken to control the confined water. In such a case, it is necessary to overcome hazards caused by the confined water, such as water inrush, and also reduce the harm to the surrounding building (structures). This paper discusses the ultra-deep foundation dewatering technology based on the successful case of Shanghai Shanda dewatering recharge works close to Metro line 2, 4, and 9. |
