| 摘 要： | GFRP桥面铺装是GFRP桥面板组合梁桥行车体系的重要组成部分。本文采用有限元分析软件对车辆荷载作用下GFRP桥面铺装层的应力分布情况进行了分析,得到了计算铺装层最大拉应力的控制荷位,并计算了在此荷位下GFRP桥面铺装层中的应力水平。研究了GFRP桥面铺装层中的应力、应变分布规律。根据分析结果,提出了大广高速6号跨线桥及类似GFRP桥面铺装的设计指标。

| Abstract: | Pavement on GFRP bridge deck is an important part in vehicle system.The distribution of stress in the pavement is analysed with FEM software.The controlling load position is found and the stress in the pavement is computed under the load position.The distribution of the stress and strain in the asphalt concrete surfacing is studied.Based on analysis results,the design indexes of the No.6 flyover bridge of Daguang Highway are proposed. |
