摘　　要：随着科学技术的发展,槽形梁越来越多地被应用在铁路施工中。槽形梁能够满足铁路行车净空的高度要求;主梁腹板作为主要受力构件,既兼备减小行车噪音,又能防止车辆倾覆。有节省钢材保养维护方便的优点,本文阐述了槽形梁在铁路工程中的施工工艺重点,讨论了施工过程中的工艺技术,最后提出控制槽形梁在工程施工过程中的质量意见。With the development of science and technology,trough beams are more and more used in railway construction.The troughed beam can meet the height requirement of railway running headroom.As the main stress component,the web of the main beam can reduce the driving noise and prevent the vehicle from overturning.It has the advantages of saving steel maintenance and convenient maintenance.This paper expounds the key points of the construction technology of the troughed beam in railway engineering,discusses the process technology in the construction process,and finally puts forward the quality control of the troughed beam in the construction process.
