高性能轻型组合桥面结构铺装实验研究

Experimental research on high-performance light-style composite bridge deck structure paving

结合某连续钢箱梁桥基本概况,对桥面铺装前后横肋、纵肋、面板三种构件及不同构件连接部位的受力或变形状况进行了试验检测,结果表明STC桥面铺装可以明显降低U肋与面板连接部位局部应力,但U肋与横隔板连接部位弧形缺口处的改善效果不明显,对U肋与箱梁腹板连接部位的改善效果有限。

Combining with the continuous steel bridge conditions,the paper carries out stress and deformation test and detection of horizontal lib,vertical lib and face-plate and various structural parts before and after bridge deck paving. Results show that： STC bridge deck paving can obviously reduce local stress of U lib and face-plate connection parts,however,the improvement effect of U lib and horizontal isolating-board connection part at arch notch is not so perfect,furthermore,the improvement effect of U lib and box-girder connection part is good enough.
