明珠二期工程南浦大桥地下车站临江侧端头井结构计算

Structural Design of the river-side Shield Working Shaft at the Underground Station of Nan Pu Bridge in the Second Phase Project of Shanghai Pearl Line

详细地介绍了上海市轨道交通明珠二期工程南浦大桥站临江侧端头井(东端头井)的结构计算,该端头井是目前国内唯一的软土盾构隧道上下近距离交叠施工的盾构出发井和到达井,也是当前上海市基坑开挖最深的地铁车站端头井,该文对这种特殊类型端头井的设计将提供重要的参考。

This paper introduces the structural calculation of the river side shield working shaft at the underground station of Nan Pu Bridge in the second phase of Shanghai Pearl Line. This shield working shaft is the sole one that serves both as a starting shaft and as an arrival shaft in the course of up-down overlapping tunnel construction at close distance in soft soil of China, and it is the deepest shield working shaft of metro station in Shanghai. What expati ated in this paper will contribute to the design of such a kind of special shield working shaft.
