Orthotropic steel bridge deck weld fatigue reinforcing structure and reinforcing method thereof
The invention provides an orthotropic steel bridge deck weld fatigue reinforcing structure and a reinforcing method thereof. The orthotropic steel bridge deck weld fatigue reinforcing structure comprises a steel bridge deck top plate and a U-shaped rib welded to the lower surface of the steel bridge deck top plate, and the area with the fatigue cracking risk or the area with fatigue cracks at the welding position between the U-shaped rib and the steel bridge deck top plate is set as a fatigue vulnerable area, and a reinforcing plate is arranged on the upper surface of the steel bridge deck top plate and corresponds to the fatigue vulnerable area. According to the invention, construction is easy and convenient, fatigue crack initiation or development of the orthotropic steel bridge deck can be effectively inhibited or slowed down, and the fatigue life of the orthotropic steel bridge deck is greatly prolonged.
本发明提供一种正交异性钢桥面焊缝疲劳加固结构及其加固方法。该正交异性钢桥面焊缝疲劳加固结构，包括钢桥面顶板以及焊接于所述钢桥面顶板的下表面的U肋，设定所述U肋与钢桥面顶板之间的焊接处存在疲劳开裂风险的区域或已经存在疲劳裂纹的区域为疲劳易损区域，在所述钢桥面顶板的上表面且对应所述疲劳易损区域的位置处设有加固补强板。本发明施工简便，能够有效抑制或减缓正交异性钢桥面板的疲劳裂纹萌生或发展，大幅提高正交异性钢桥面板的疲劳寿命。
