大跨度隧道穿越城市建筑群的设计及施工思考

在市政建设中,针对隧道埋深浅、穿越城市密集建筑群、地质条件差、隧道跨度大、双洞之间间距小的特点,为保证施工的正常进行和对地表建筑物的影响最小,对设计方案和施工方法进行优化,达到了较好的效果。

In the municipal building, for the tunnel shallow, dense buildings across the city, poor geological conditions, the tunnel span, two- hole spacing between the characteristics of small, in order to ensure the normal construction and minimal impact on surface structures, the design optimization program and construction methods to achieve good results.
