摘　　要：随着铁路工程建设不断发展,山区铁路进入新一轮建设高潮。山区铁路地形地质复杂,枢纽范围环境敏感性强,受控因素多,因此,线路进入枢纽范围后,常采用不同速度目标值予以克服,故出现同一条线路多隧道断面的情况。如何安全合理通过不同断面隧道运架箱梁,成为山区铁路工程建设中值得研究的课题。文章结合某山区客运专线铁路工程,以GY枢纽多断面隧道群箱梁运架方案为例,在现有的施工技术手段基础上,从工程设计方案现状入手,着重技术经济层面,探讨科学合理的箱梁运输与架设方案,以此为工程建设顺利开展提供技术支持。With the continuous development of the railway industry, the mountain railway construction comes into a new age, different target speed values are often adopted when the line goes into terminal scope and multi tunnel section oc-curs in the same line. Thus transportation and erection of box girders via different sections safely and rationally is a valu-able research topic in mountain railway engineering construction. Combining with certain mountain railway engineering, taking GY terminal as an example, focusing on technical and economic aspects based on current construction technique means and engineering design plan, The paper discusses scientific and reasonable transportation and erection scheme of box girders to provide technical support for the engineering construction to be carried out smoothly.
