隧道工程施工地表变形对既有建筑物影响及对策研究

The study on the effect and countermeasure to the tunnel engineering between it and the existing buildings——Taking the Dong Hai tunnel project in Quanzhou as an example

隧道工程作为重点建设工程,其建设过程不容有失,由于隧道工程情况复杂,存在种种难点问题,如何确保隧道施工对既有建筑物降至可接受范围内,目前并没有较为成熟的经验可循,为此,针对隧道工程的重点难点问题特别是对地表变形对既有建筑物影响进行分析具有十分重要的理论与现实意义,本文以东海隧道为例,从建筑物沉降、倾斜、结构应力三个方面探讨隧道工程施工地表变形对既有建筑物影响。其研究成果不仅可为东海隧道的顺利建设保驾护航,同时还可为其他城市隧道建设提供参考。

Tunnel project is a key construction project and its construction process is very important. There are all kinds of difficult problems in the tunnel engineering. How to ensure the safety of tunnel construction between the tunnel engineering and the existing buildings is difficult and there is no mature experience to follow. Therefore,the analysis has a very important theoretical and practical significance. This paper analyzed the effect and countermeasure to the tunnel engineering between it and the existing buildings,and it took the Dong Hai tunnel project in Quanzhou as an example from the building settlement,tilt and structure stress. structure stress three aspects. The research results was not only uesed in the Dong Hai tunnel project in Quanzhou,and it can also provide a reference for tunnel construction in other cities.
