横洞爬坡法在铁路隧道施工中的应用

Application of transverse gallery climbing method in railway tunnel construction

随着铁路工程的快速发展,中长隧道工程越来越多,为了加快施工进度,通常增设计横洞辅助施工,其施工技术成为控制隧道施工质量及进度的影响因素之一。本文通过对某铁路隧道中横洞爬坡法的研究,以期为类似项目施工提供借鉴。

With the rapid development of railway engineering, there are more and more medium and long tunnel construction projects. In order to speed up the construction process, transverse gallery are usually designed to assist in construction. Its construction technology has become one of the factors affecting the quality and schedule of tunnel construction. In this paper, through the study of the climbing method of horizontal tunnel in a railway tunnel, it is hoped to provide reference for similar project construction.
