摘要

分析了国内外规范中关于车辆桥墩撞击力取值的优缺点,设计并制作了墩柱、车辆模型。完成了不同墩柱尺寸、不同小车撞击速度条件下的小车墩柱撞击试验。采集了撞击过程中墩柱及小车模型的动应变和加速度,分析了撞击过程中加速度及应变的时程特点。研究结果表明,撞击力的大小与小车撞击速度和墩柱尺寸呈一定相关性。研究结果为进一步研究实际车辆与桥梁撞击提供了数据参考。

Abstract

According to domestic and foreign specifications, horizontal forces for piers subjected by vehicle collision were discussed. The models of pier and small vehicle were designed and made. Experiments of small vehicle collision with piers were tested with different pier dimensions and varied small vehicle velocities. Testing data about dynamic strain and acceleration of pier models, acceleration of small vehicle model were collected. Based on the analysis of testing data, it can be seen that the collision force is related to the collision velocity and the pier size. The research results provide the data support for further research of the real vehicle-bridge collision.
