摘要
当前,我国隧道高地热段的设计已取得一定成就,但在实际施工时,受到地形等条件的制约,往往需针对性地采取相关措施。通过渝黔铁路天坪隧道高地热段的设计及施工实例,分析了地热对隧道工程施工产生的不利影响,系统地阐述了隧道在高地热段采取的各种降温及保证快速施工的技术措施,最终保证了施工人员的安全和工程顺利推进,为今后类似工程的设计提供参考。
At present,some achievements have been made in high thermal ground design of tunnels in China.However,due to the restriction of topography and other conditions,relevant measures should be taken in practical construction.Based on the high geothermal section of Tianping tunnel in Chongqing to Guiyang railway project,taking the design and construction of this project as an example,analyzes the geothermal adverse influence on tunnel engineering construction,systematically expounds all kinds of cooling and guarantee quick construction measures used in the high geothermal section of tunnel,finally,the safety of the construction personnel is guaranteed,and the smooth progress of the project is provided for the design of similar projects in the future.
