| Abstract: | Ba-zhun rail is designed as reserved continuous welded rail.In the paper studies is carried out on the substitu-tion of the Ba-zhun rail with continuous welded rail.In design,the design parameters and track temperature is determined according to the engineering features.And checks are made on the rail intensity,stability,gap value and girder-rail’s rap-id relative displacement of continuous welded rail in large span continuous beam bridge to ensure the design demand.Mean-while,a feasible designing scheme for the structure of the continuously welded rails is proposed to provide references for continuous welded rail replacing in Ba-zhun rail. |

| Keywords: | track continuous welded rail fastening-down temperature of rail rail expansion joint |
