摘　　要：桥梁仿真实验是研究桥梁结构性能的重要手段,其中的对静载实验仿真是评价桥梁质量和评估实际承载力的有效方法.采用1?25的精细化车辆模型与有机玻璃桥梁缩尺模型对实际桥梁的静载实验进行了物理与虚拟仿真,其中,虚拟仿真采用MIDAS有限元软件分析,而物理仿真采用缩尺模型实验研究.将物理仿真与虚拟仿真实验结果进行比较,发现两者基本一致,验证了此种方法的精确性与有效性.Simulated experiment of bridge is an important means to study the performance of bridge structures, in which simulation of static loading experiment is an effective method to evaluate quality of bridge and assess bearing capacity of bridge. The study utilizes fine vehicle model and plexiglass model of bridge with the same geometric reduced scale of 1：25 to conduct physical simulation and virtual reality of the actual bridge static loading experiment. In the process, the virtual reality utilizes finite element software, MIDAS, for analysis and the scale model experiment is used to study the physical simulation. The results of physical simulation and virtual reality are compared and found that the both are significantly similar. It is concluded that the physical simulation and virtual reality complement each other and play an important role in research and teaching of bridge engineering.
