在目前的道路施工中,依然存在着许多的问题。在进行公路的建设时,进行大断面隧道的开挖不可避免。本文主要是介绍了大断面公路的一些特点,然后介绍其基本的施工原则以及施工技术。并且对全断面法和双侧壁方法进行了分析,选用合适大跨度隧道的施工方案和技术,以此为大断面隧道施工提供有力的参考。
In the current road construction, there are still many problems. In the construction of highways, the excavation of large cross-section tunnels is inevitable. This paper introduces some of the characteristics of large section highway, and then introduces its basic construction principles and construction techniques. And the full-face method and the double-wall method are analyzed, and the construction scheme and technology of the suitable long-span tunnel are selected to provide a powerful reference for the construction of large-section tunnels.
