摘　　要：为研究车站地层系统中关键构件中柱抗震性能,以车站地层系统为研究对象进行虚拟混合试验分析。建立基于OpenSees平台的车站地层系统计算模型。利用连接单元连接两个数值分析模型,进行虚拟混合试验。选取车站中柱作为附属程序,其余部分作为主程序进行动力时程分析。通过混合试验结果与有限元模拟结果对比分析,验证了本文所建立的混合试验系统能够准确地反映地震作用下车站地层系统中柱构件的力学行为。虚拟混合试验的可靠性为地下结构物理混合试验设想提供了可行性验证。In order to investigate the dynamic seismic behaviors of central column in soil station system,the virtual seismic hybrid simulation was conducted.A soil station OpenSees model was performed.The virtual hybrid simulation was fulfilled with the adapter element.The bottom half central column was treated as the slave program,while the rest of the soil station system was treated as the master program.Hybrid test results were compared with analytical results.The results show that the system can accurately reflect the mechanical properties of the central columns in soil station system.The reliability of the virtual hybrid test provides a theoretical basis for the experimental implementation of the underground structure hybrid simulation process.
