Study Of Influence For An Hua Subway Station Near The Bridge

With the urban population increasing rapidly, more and more crowded urban traffic become a trend, the development of public transport, urban rail transit city ground to avoid congestion and make full use of the space and fast-time, is the rapid development of the construction, the construction process will inevitablya series of problems encountered close to housing construction, bridge construction, and in the process of the new subway project,the construction of the building will have impact, but also the impact of existing buildings. How to ensure the subway excavation. Construction under the premise of the original building has become an important topic.Based on the Beijing subway No.8line two of Anwar bridge station near Anwar Bridge-impact study by numerical simulation analysis, on-site monitoring of the impact of the new above metro station near the bridge system analysis and research. Research content is as follows:(1) Subway station construction near the bridge,by using FLAC3D simulation to calculate the number of viable Construction Method at the station to determine the analytical methods and parameters, forecast bridge construction bridge foundation subsidence, tilt and deck cracks.(2) Collected through the static water ievel, inclinometer beam displacement meter instrument bridge construction process of deformation data were analyzed and simulated data. Get deformation near the bridge station excavation and construction law.(3) Subway station construction may cause deformation of the bridge need to reinforce measures to restore the deformation caused by the excavation, so it FLAC3D simulation of a variety of possible reinforcement measures, reasonable reinforcement program.
