摘要
文章以广州市增城区凤凰城地下调蓄池工程为背景,在上软下硬地质特征、地下水丰富且水位较浅及周边临近既有建(构)筑物等复杂环境下,选择具有支挡和止水双重作用的地下连续墙作为基坑支护体系主体结构.监测结果表明:该项目基坑变形和周边(构)筑物沉降均在允许范围内,且无突变情况,未触发预警,施工全过程处于安全可控状态.
Abstract
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.
