明挖隧道整体装配式结构接头形式的研究以及应用

Research and Application of Joint Type of Integral Assembled Structure in Excavated Tunnel

摘要:

对于大型或超大型城市的核心,利用在地下修建隧道的方式以缓解交通压力,早已成为了城市建设、经济发展以及交通脱困的最无奈的解决方式。但由于周边环境条件的限制，此类隧道的施工方式基本仍停留在最为传统的施工工艺上。隧道的施工周期长，环境影响大，建设投资及损耗也大。装配整体式结构的出现和应用，可以有效的解决上述问题。结合武宁路快速化改建工程Ⅱ标整体式结构试验段，对装配整体式结构街头的形式进行了分析及设计，推动配整体式结构在其他明挖隧道工程中的应用，并为后续的相关工程带来一点借鉴。

Abstract:

For the core of large or super large cities, the method to build the underground tunnel in order to ease the traffic pressure has already become the most helpless solution for the urban construction, economic development and traffic congestion. However, due to the limitations of the surrounding environmental conditions, the construction method of this kind of tunnel basically remains in the most traditional construction technology. The construction period of tunnel is long, the environmental impact is large, and the construction investment and loss are also large. The appearance and application of integral assembled structure can effectively solve the above problems. Combined with the integral structure test section of Section II of the rapid reconstruction project of Wuning Road, the street form of integral assembled structure is analyzed and designed in order to promote the application of integral assembled structure in the other excavated tunnel projects, and provide some reference for the subsequent related projects.
