铁路桥梁横向变形限值标准问题的研究

A Research over the Limit Value Standard for Transversal Deformation of Railway Bridges

铁路桥梁横向刚度一般通过横向变形限值来体现 ,其标准是一个十分复杂的问题 ,随着列车速度的提高 ,尤其是货物列车速度的提高 ,这一问题变得十分突出。通过对国外最新相关规范标准和研究的综合分析 ,结合我国铁路提速的桥梁动载试验数据 ,给出新建客车 2 0 0km/h、货车 12

The transversal rigidity of railway bridges is generally embodied through transversal deformation limit value, standard of which is a complex issue, and the issue becomes highlighted with increase of train speed, especially freight train. A limit value standard for transversal deformation of railway bridges on a new mixed passenger (200 km/h) and freight (120 km/h) railway was given by analyzing latest relevant standards in foreign countries and live load test data of bridges in China.
