摘　　要：工程结构灾变问题始终是社会关注焦点和学界研究热点,近年来,我国隔震结构数量增长迅猛,但其构造特殊,已有灾变研究成果无法完全适用。该文针对隔震结构潜在灾变问题,从倾覆倒塌和连续倒塌主要灾变模式入手,结合国内外相关领域最新研究成果,系统性总结和探讨隔震结构灾变机理、灾变模式和防控对策,以期为今后隔震结构灾变研究提供参考。The catastrophic problem of engineering structure has always been the focus of social attention and research hotspot.In recent years,isolated structures are growing in a large number in China.However,because of its special construction,the existing research results on catastrophe cannot be fully applied.This paper focuses on the potential catastrophic problems of isolated structures,starting with the main catastrophic models of overturning collapse and progressive collapse,and combining the late research results in related fields,systematically summarized the catastrophe mechanism,catastrophe prevention and control measures of the base-isolated structure,hoping to provide reference for fiiture research on such structure.
