摘　　要：考虑土-结构相互作用(SSI)的大跨度空间结构抗震研究对于实现大跨度空间结构精确化分析,保障结构抗震安全性具有重要意义。为了更好地应用已有大跨空间结构考虑土-结构相互作用的研究成果,分别对土-结构相互作用研究分析方法、框架结构SSI效应影响分析、地下-土-地上结构相互作用研究现状、大跨度空间结构与下部支承体系协同工作及考虑SSI对大跨度空间结构动力性能的影响等方面的研究成果进行了梳理。结果表明:已有土-结构相互作用分析方法及计算模型对于大跨度空间结构的适用性有待商榷;框架结构SSI效应和大跨度空间结构与下部支承体系协同工作的研究相对成熟,其成果可供借鉴;带有大型复杂地下结构的大跨空间结构SSI效应显著;现有研究多以数值模拟为主,试验技术的发展对大跨空间结构土-结构相互作用抗震理论的验证至关重要;未来需要进一步研究实用的简化计算模型及分析方法、地下结构-土-大跨度空间结构体系、强震失效倒塌机理及减隔震研究、试验研究、参数分析、复杂效应耦合等。The seismic research of large-span spatial structures considering soil-structure interaction(SSI)is of great significance for achieving precise analysis of large-span spatial structures and ensuring seismic safety of structures.In order to better apply the existing research results on soil structure interaction in large-span space structures,the research and analysis methods of soil structure interaction,SSI effect analysis of frame structures,current research status of underground soil above ground structure interaction,collaborative work between large-span space structures and lower support systems,and the impact of SSI on the dynamic performance of large-span space structures were summarized.The results indicate that the applicability of existing soil structure interaction analysis methods and calculation models for large-span spatial structures needs to be discussed.The research on the SSI effect of frame structures and the collaborative work between large-span spatial structures and lower support systems is relatively mature,and its results can be used for reference.The SSI effect of large-span spatial structures with large and complex underground structures is significant.The current research mainly focuses on numerical simulation,and the development of experimental techniques is crucial for verifying the seismic theory of soil structure interaction in large-span spatial structures.In the future,further research is needed on practical simplified calculation models and analysis methods,underground structure soil large-span spatial structure systems,strong earthquake failure collapse mechanisms and seismic isolation research,experimental research,parameter analysis,complex effect coupling,etc.
