分析了铁路简支梁及连续梁桥在高速列车作用下的冲击系数与车速的关系,并对这两种桥型的冲击系数进行了比较。计算表明,连续梁桥的冲击系数比简支梁桥在相同条件下有一定减小
The relationship between the impact coefficient and the vehicle speed under the action of high-speed train is analyzed, and the impact coefficients of the two bridges are compared. The calculation shows that the impact coefficient of continuous girder bridge is lower than that of simple girder bridge under the same conditions
