摘要
明珠线二期宜山路车站南端头井区域深基坑(1～7轴)的环境保护要求高,施工条件复杂,为此,基坑施工过程中综合采用了多种施工技术措施,其中包括选用地下连续墙作为围护结构;选用旋喷桩、注浆加固、承压降水井点等方法进行软土地基加固,选用钢支撑、钢筋混凝土支撑、钢框架及装配式钢牛腿等组合支撑体系;并充分利用了时空效应原理和信息化管理手段,取得了较好的效果。
Deep excavation at south shaft of Yishan Road Station of Shanghai Rail Transit Pearl Line (Second Phase) situates under a complicated construction condition which requires a high environment protection. Several construction technologies are applied including diaphragm wall as retaining structure, jet grouting pile, grouting and artesian aquifer dewatering for soft ground stabilization and steel support, reinforced concrete support, steel framework and fabricated steel bracket for supporting system. In addition, fully use of theory of time-space effect and information management are proved to be effective.
