摘　　要：本文论述桥梁刚度与车速的关系、简支梁挠度曲线和桁梁挠度的计算与实测方法，并对大跨度桥梁的刚度提出要求。The relations between the rigidity of railway bridges and the running speed of trains,the deflection curves of the simply supported beams and the calculation and practical observation methods for the deflection of the trusses are described and discussed. The requirements on the rigidity of the long span railway bridges are also proposed.
