【摘要】 明珠线二期中618m的宜山路车站是目前上海地区在建的最长的地下车站,基坑最深19.73m,其西侧平行于已建成的明珠一期工程宜山路高架车站和区间,最近处仅3.8m,东侧相邻十几栋7层楼的民居,最近处仅0.26m。车站周边环境复杂,环境保护要求高。设计根据车站周边工程环境实际情况及一级基坑变形控制保护等级技术要求,结合宜山路车站施工工期具体情况,围绕确保周边环境安全的核心提出车站基坑设计的总体方案,运用信息化施工和时空效应控制技术原理,通过计算对施工提出明确的要求,将设计与施工相结合,全过程跟踪施工,确保设计质量的真正落实,从而确保了明珠一期的正常运营及民宅的安全,取得了显著的社会和经济效益。更多还原

【Abstract】 The 618m long and 19.73m deep Yi Shan Road Station of Shanghai Rail Transit Pearl Line (Phase Ⅱ) is the longest underground station in Shanghai. The west part of the station is parallel, at a nearest distance of 3.8m, to the elevated rail and station of Shanghai Rail Transit Pearl Line (Phase Ⅰ) and the east part is adjacent, at a shortest distance of 0.26m to several 7-storey buildings. The complicated surrounding condition determines high environmental protection requirements. According to the technical requirements of deformation control and protection of Grade I deep excavation and based upon the site condition and construction schedule, an overall design proposal is offered with the intention to ensure the environmental safety. The feedback informational construction technology and Time-Space Effect theory are applied to make specific requirements for construction. Combine design with construction and construction tracking during the whole process to guarantee the realization of the design concept. The result is obvious that the normal operation of Shanghai Rail Transit Pearl Line (Phase I) and the safety of the buildings lead to the outstanding social and economic effects.更多还原
