| Abstract: |
| This paper mainly forcuses on the construction technology of the Shanghai Metro Line 10 which is to cross the upper operating Shanghai Metro line 1. The difficulties of the crossing section, construction measures and actual construction conditions are described and discussed. Acturally, this paper is mainly talking about how to control the implementation of the tunnel through work through the three stages of crossing tunnel, namely pre-crossing, in-crossing and post-crossing, ensuring the settlement deformation of the through tunnel and its upper part of the buildings in safe and controllable range. It is through the discussion of the crossing construction to provide a certain reference value to the upper part crossing of future trail traffic. |
| Key words: crossing the upper tunnel the deep constructionthe of the shallow buried control of the tunnel settlement |
