中文摘要：
淮安雨润国际广场工程为地处市中心的超大面积深基坑工程,该工程周边环境保护要求极高,基坑开挖深度范围内及基底以下巨厚的粉土、粉砂层富含地下水,对基坑工程隔水设计提出了极高的要求。为确保基坑隔水效果、保护周边环境,本工程在江苏地区首次采用了由TRD工法构建的等厚度水泥土搅拌墙隔水帷幕,有效的隔断了地下水,确保了基坑和周边环境安全。详细介绍了淮安雨润国际广场基坑工程的设计,并着重阐述了TRD工法等厚度水泥土搅拌墙隔水帷幕在本工程中的实施效果。
英文摘要：
The foundation pit of Huai'an International Square located in the city center is a super-large and deep excavation project. The requirement for protection of its adjacent surroundings is quite strict. The silt soil with a great deal of water is widely distributed in this excavation. In order to ensure the waterproof effect of the excavation and a protect the surrounding environment, the TRD wall is firstly used in Jiangsu areas, which is a new retaining structure for excavation, or named the constant thickness cement-soil wall constructed by the TRD method. It is successfully used to cut off groundwater and to ensure the safety of the surrounding environment in the project. Based on the deep excavation project of Huai'an International Square, the characteristics,application conditions and key design technology of the new excavation retaining structure “TRD” are introduced.
