摘　　要：为了研究新型钢-混组合桥面系的受力性能,以某大跨度钢-混组合桥面系悬索桥为工程背景,对该桥面系3个节段的1/4缩尺模型进行静载试验。然后,采用大型有限元软件ANSYS,对试验模型进行数值模拟。研究结果表明:数值模拟结果能够与试验数据很好地吻合,并起到验证的作用;该桥面系在静载试验过程中充分发挥了各自的材料性能,表现出较高的抗弯刚度和承载能力;新型钢-混组合桥面系在静力荷载作用下能够协同受力且受力均匀,不易产生局部应力过大的现象。In order to investigate the mechanical performs of the new steel-concrete com-posite deck system,the steel-concrete composite bridge deck system of a long-span sus-pension bridge was cited as an example,the static test was carried out on themodel of the three sections of the bridge deck system and the large-scale finsoftware ANSYS was used to simulate the experimental model. It can be concluded that the numerical simulation results agree well with the experimental data and play a role of verification. The material properties of the bridge deck system are fully utilized,and areshown with high flexural rigidity and bearing capacity in the process of The new steel-concrete composite bridge system can work together and force evenly un-der the action of static load,and it is not easy to cause the local stress too big.
