The Application of Underground Continuous Wall in Storage Tank Foundation Pit Support Engineering under Complex Environment
Based on the Phoenix City underground stor-age tank engineering in Zengcheng District of Guangzhou City,this paper selects the underground continuous wall with dual functions of support and water stop as the main structure of the foundation pit support system under the complex environment of the upper soft and lower hard geological characteristics,rich groundwater and shallow water level and being adjacent to existing buildings(struc-tures).The monitoring results show that the deformation of the foundation pit and the settlement of the surrounding buildings(structures)of the project are within the allow-able range,and there is no sudden change and no warning triggered,and the whole construction process is in a safe and controllable state.
