摘要
基于横向风中铁路 16 m、2 4m预应力混凝土 T形简支梁桥单体、YZ2 2 型车辆与16 m T形简支梁桥组合体、双层旅客列车车辆与 2 4m T形简支梁桥组合体分别在不同来流攻角下的数值模拟结果 ,结合现行《铁路桥涵设计基本规范 TB10 0 0 2 .1- 99》中有关桥梁设计风荷载的规定 。
Based on the numerical simulation of 16m,24m prestressed concrete free supported T beam bridge,the YZ 22 vehicle on the 16m free supported T beam bridge,and the double deck vehicle on 24m free supported T beam bridge in crosswing with different angle of attack,the results indicate that when designing railroad free supported T beam bridge,the figure coefficient and wind loads should be adjusted,compared with the Fundamental Code Design on Railway Bridge and Culvert.
