摘　　要：本文以贵州省安顺至盘州高速公路项目为例,以项目百石荞特大桥跨中缅天然气管道施工工点为背景,论述了采用“盖板防护”+“贝雷梁钢便桥”两种主动与被动相结合的跨天然气管道施工防护工程的设计与应用,并采用有限元分析软件分析了钢便桥的强度、刚度,满足设计规范要求,可为类似跨管涵等工程施工提供借鉴经验。This article takes the Anshun Panzhou Expressway project in Guizhou Province as an example,and takes the construction site of the Baishiqiao Extra Large Bridge crossing the China Myanmar natural gas pipeline as the background.It discusses the design and application of two active and passive combination of"cover plate protection"and"Bailey beam steel temporary bridge"for cross natural gas pipeline construction protection engineering.Finite element analysis software is used to analyze the strength and stiffness of the steel temporary bridge,which meets the requirements of design specifications and can provide reference experience for similar cross pipe culvert construction projects.
