| 摘 要： | 中国桥梁规范对于桥梁冲击系数的规定比国外相关规定偏小，而对于老旧桥梁其桥面平整度随荷载运行而逐步恶化，此时桥梁的冲击系数将大幅增加。因此提出在旧桥评估和加固方面，其冲击系数应给予适量放大，并通过模拟试验验证这一结论。

| Abstract: | Our country bridge standard is small regarding the bridge impact factor＇s stipulation contrast overseas related stipulation, but regarding obsolete bridge its bridge floor roughness along with load movement but worsens gradually, this time the bridge impact factor largely will increase. Therefore, that impact factor should suitably increase was proposed for obsolete bridge evaluation and reinforce, moreover, the conclusion was demonstrated by some simulate experimentation. |
