摘　　要：采用非线性有限元分析程序ABAQUS,对某CFRP体外预应力公路桥进行数值模拟,并与荷载试验数据进行对比分析。试验结果表明,软件模拟所得的CFRP体外索索力变化趋势,与实测结果及理论计算结果相同,索力增量同实测结果相符,主梁和CFRP体外索表现出良好的协同工作性能,商业程序能较好模拟实桥服役工况下受力特性。In this paper,the nonlinear finite element analysis program ABAQUS is used to simulate a CFRP externally prestressed highway bridge.Compared with the load test data,the test results show that the change trend of CFRP external tendon force simulated by the software is in accordance with the measured and theoretical calculated results,and the force increment is consistent with the measured results.The beam and CFRP external tendons show great compatible working performance.The commercial program is able to simulate the mechanical characteristics of the real bridge under service conditions.
