桥梁冲击系数的探讨

Approach of Impact Coefficient of Bridge

采用汽车激振法．测试吉林市九站松花江特大桥的冲击系数１＋μ。测试结果表明．对于跨径大于４５m的桥梁在设计时应该考虑冲击作用。

With the method of vibration by automobile, the impact coefficient of Jilin Jiuzhan Songhuajiang River-bridge was tested, The results show that the impact affect of bridge span over 45 m should be considered in the course of designing.
