轨道顶面南湖路道路路基建设方案研究

Study on Roadbed Construction Scheme of Nanhu Road above Metro

随着城市化的进程的不断推进,地铁隧道和城市道路的覆盖面都越来越广,相互间的线路错综复杂。地铁隧道上方的道路实施对地铁运营安全影响问题突显,由于道路路基开挖及填高路堤等原因,常对地铁隧道结构造成附加应力影响。以苏州市地铁4号线上方南湖路的实施为依托,根据轨道公司的要求,针对性地提出相关建设建议和措施,以期为类似工程提供有益参考。

With the continuous promotion of urbanization progress, the coverage of metro tunnel and urban road is getting wider and wider, and the lines between the metro tunnel and urban road are intricate. The road implementation above the metro tunnel greatly affects the safety of metro operation. The roadbed excavation and the high filled embankment of road often cause the additional stress influence on the metro tunnel structure. Taking the implementation of Nanhu Road above Suzhou Metro Line 4 as an example, and based on the requirements of metro company, this paper puts forward the targeted construction proposals and measures in order to provide the beneficial reference for the similar projects.
