摘　　要：对FRP-钢组合结构公路桥研制过程中的关键技术进行了研究,通过GFRP桥面板的设计与加工、有限元分析和试验研究,研制出适用于我国公路桥梁用的重型FRP桥面板。将GFRP桥面板与波形腹板H型钢梁组合起来,建成我国第一座FRP-钢组合结构公路桥。对GFRP-钢组合结构公路桥梁结构进行成桥荷载试验。试验结果表明,FRP-钢组合结构桥梁处于安全受力状态,满足设计荷载下的使用要求。The construction technology of FRP-steel composite bridge is researched through the development process. The FRP bridge deck that used in bridge structure is developed through the design and fabricate, as well as the finite element analysis and experimental research of GFRP bridge deck. And the first FRP-steel composite bridge in China is built with GFRP bridge deck and steel H girder with corrugated web. Load test of the composite bridge is made, and the result shows that the structure is in a safe state and meets the requirements under the design load.
