摘要
针对某在建大跨度斜拉桥正交异性板公路桥面,对焊接制造重要部位进行疲劳试验研究。分别得出不同构造细节的S-N曲线方程,然后与设计曲线进行对比,对实际结构的焊接细节疲劳性能进行评价,计算分析结果以及疲劳试验所得的参数可为工程的进一步开展提供依据。
Based on an orthotropic plate of long-span cable-stayed bridge constructing, fatigue experimental research of important positions is done. S N curve equation of different construction detail is obtained, then compared with design curve, the fatigue performance of welding detail of practical structure is evaluated, which can put forward basis for further developing of the engineering.
