中文摘要：
考虑群桩－土相互作用影响，对梁式桥在顺桥向水平地震作用下的子结构拟动力试验方法进行了研究。在建立的结构试验模型中，可以取桥梁支座、桥墩或桩基础作为试验子结构置于异地实验室进行试验实测，其余部分进行数值模拟。基于网络化结构实验室NetSLab系统，开发了考虑群桩－土相互作用的梁式桥远程协同子结构拟动力试验程序。进行了一系列梁式桥远程虚拟子结构拟动力试验，并将试验结果与SAP2000时程分析结果进行了对比，验证了试验程序的可靠性。
英文摘要：
With consideration of the effect of pile group - soil interaction, the substructure pseudo - dynamic test method of beam bridge under horizontal earthquake excitation along bridge direction was studied. In the established structural model for testing, the bridge bearing, pier, and pile foundation can be tested in laboratories, while the other parts can be simulated numerically. Based on the networking structural laboratory system NetSLab, a remotely collaborative substructure pseudo - dynamic test program for beam bridge considering the pile group - soil interac- tion was developed, and a series of virtual substructure pseudo - dynamic test of beam bridge were conducted and results were compared with that calculated by SAP2000. The results verified the reliability of the program.
