烟台西山城市公路隧道设计与施工

Design and construction of a city tunnel

比较山岭公路隧道而言,由于城市人口、设施较为密集,隧道施工对周边环境影响较大,因而城市公路隧道在设计、施工等方面应有更高的要求,即在充分考虑隧道使用功能以及工程造价的同时,应尽可能将隧道施工对周边环境产生的影响降至最低。因此,坚持“以人为本”、重视隧道景观设计、加强环境保护将成为城市公路隧道建设的重要理念。文章结合烟台市西山隧道工况,介绍了城市公路隧道设计方案、施工方法以及环境保护措施。

Construction of a city highway tunnel will impact on the environment to a higher degree as compared with that of tunnels in mountainous areas, since urban population and buildings are very dense. So the design and construction of a city highway tunnel should be performed with a higher standard, trying to minimize the impact of construction on the environment while considering the functions as well as the construction cost of the tunnel. Therefore, aiming at the＂ people first＂ premise, paying attention to scenic design of the tunnel and to the environ- mental protection will become the important concept for the city highway tunnel construction. This article introduces the design options, construction methods and environment protection measures for a city highway tunnel.
