越江隧道的盾构工作井具有埋地深、尺寸大、工况复杂等特点,且是工程中最先开工和最后完工的特殊结构。本文以上海新建路越江隧道浦西工作井为工程背景,根据工作井施工期间的实际工况和受力特点,对超大超深盾构工作井的围护和主体结构分别进行了平面和三维分析,为今后越江、跨海隧道盾构工作井的设计提供有益参考。 The shield tunnel of the tunnel of the tunnel has the characteristics of being buried deep, large in size and complex in working conditions, etc., and is the first special structure that has been started and completed in the project. In this paper, the Puxi working well in the cross-river tunnel of Xinjianlu road in Shanghai is taken as the engineering background. According to the actual working conditions and stress characteristics during the construction of the working well, the envelope and the main structure of the super- It provides a useful reference for the design of the shield work well in the cross-sea and cross-sea tunnel in the future.
