摘要
为在桥梁护栏碰撞试验中,提取桥梁设计的有效数据,需设计一种可模拟桥梁翼缘板的护栏试验基础。该文通过理论分析和有限元仿真计算,使该试验基础能够为确定护栏和翼缘板地角螺栓连接强度要求指标和混凝土桥梁翼缘板配筋结构力学性能要求指标提供数据支持。结果表明,试验护栏基础可以在桥梁护栏碰撞试验中使用。
In order to get effective data of the bridge design from bridge barrier impact test,a barrier foundation is required to design to simulate bridge flange plate. The foundation is proved to be able to supply data to meet bolt connection strength index requirement between barrier and bridge flange plate and meet steel beam design index requirement in bridge flange plate by theory analysis and finite element imitating calculation. The barrier foundation can be used in the bridge barrier impact tests.
