浅谈连拱隧道和小净距隧道的设计与施工

On the design and construction of continuous arch tunnel and tunnel with small clear distance

分别对连拱隧道和小净距隧道的断面形式和开挖方法进行了介绍,并着重对小净距隧道施工过程中夹岩不同厚度的处理手段进行了阐述,以推广连拱隧道和小净距隧道在以后公路建设中的应用。

This paper introduces the cross-section form and excavation method of continuous arch tunnel and small clear-distance tunnel,and illustrates treatment methods for interlaid rock with different thicknesses in the construction process of tunnel with small clear-distance,in order to popularize the application of continuous tunnel and small clear-distance tunnel in highway construction in mountainous area.
