随着我国铁路事业的高速发展,为实现在缩短铁路里程的同时增加运力,双线隧道施工也愈来愈被广泛地应用起来。本文就结合工程实例,对三种不良地质及特殊地段情形下铁路双线隧道的施工技术进行研究,分别为对铁路双线隧道塌方处理施工技术、下穿高速公路施工技术以及穿越破碎段的施工技术,以期为同类工程提供可参考借鉴。
With the rapid development of the railway industry in our country, the construction of double-track tunnels has also been applied more and more widely in order to increase the capacity while reducing the railway mileage. In this paper, the construction technology of railway double-track tunnel under three kinds of bad geology and special lots is studied in combination with engineering examples, respectively for the construction technology of the railway double-track tunnel collapse treatment, the construction technology of the next wear highway and the construction of crossing the crushing section Technology, in order to provide reference for similar projects.
