摘　　要：随着国家经济发展,铁路在建设交通强国中彰显重要地位。铁路建设经过山区段通常都是桥隧相连,采用架桥机架梁是建设过程中不可或缺的工艺,铁路过单线隧道时,断面尺寸较小,桥台距离隧道口很近,通常会出现架桥机不能正常架梁的工况。结合瓮马铁路隧道口T形梁架设施工技术的实施,对隧道口T形梁架设过程进行分析,总结了隧道口T形梁架设技术控制要点及保障措施,为同类型工程实施可提供借鉴。With the development of the national economy,railways have shown an important position in building a strong transportation country.Railway construction in mountainous areas is often connected by bridges and tunnels,and the use of bridge erection frame beams is an indispensable process in the construction process.When a railway passes through a single track tunnel,the cross-sectional size is small,and the bridge abutment is very close to the tunnel entrance,often resulting in the condition that the bridge erection machine cannot properly erect the beams.Combined with the implementation of construction technology for T-beam erection at the tunnel portal of WenG´an-Machangping railway,this paper analyzes the process of T-beam erection at the tunnel portal,summarizes the technical control points and safeguard measures for T-beam erection at the tunnel portal,which can provide reference for the implementation of similar projects.
