| Abstract: | Channel girders are rarely used in railway bridges.This paper conducts calculation and analysis of 1-32 m channel girders on Dunhuang-Geermu railway and dynamic simulation and analysis of vehicle / bridge coupling.The results show that the designed section of channel girder groove and the stresses are reasonable,and the vehicle / bridge dynamic characteristics meet the current specifications,which provide theoretical basis and scientific reference for Dunhuang-Geermu railway's safe operation and for extended application of the channel girder in the railway construction in our country. |
