| Abstract: | Shield tunneling machine passing through existing buildings or structures are the main difficulties in subway construction, and it is more difficult to pass through shallow stone arch bridge. This paper base on the background of NO. 6 section, Peng jia Bridge to Shida south Road, of Nanchang Metro construction, which passes through a two - hole shallow stone arch bridge of Yudai river. It will analyze the difficulties of the construction, the impact on the existing bridge of the shield construction and it will also introduce the appropriate countermeasures and measures which are used in construction process. Through these above analysis, it can provide certain reference for similar project. |
