摘　　要：随着铁路建设的发展,所建项目不断增多,有的经过山区地热高温地段,不但影响到隧道施工安全和效率,也给施工组织和所需费用的确定带来困难。此文以玉蒙铁路旧寨隧道地热高温段为例,从施工组织设计入手,来探讨采取的施工防护措施和降温措施,并对需要增加的相关费用进行分析。With development of railway construction, the projects are increasing constantly. Some railways pass through the geothermal high temperature area in mountain area, which not only affect the safety and efficiency of tunnel construction, but also bring difficulties to construction organization and determination of required costs. Taking the Jiuzhai tunnel of Yuxi - Mengzi railway as an example, the design of construction organization is analyzed in this paper to explore the construction protection measures adopted and measures to cool down. And the increased related costs are analyzed.
