摘要
我国是世界上自然灾害最严重的国家之一,灾害种类多样且分布广泛,部分地区存在着多灾害聚集分布的现象,各类灾害给区域内的工程结构安全带来了巨大的威胁。为推进我国工程结构抗多灾设计理论的发展,对国内外建筑结构、桥梁工程等领域的多灾害研究现状进行了系统的综述。对灾害学领域与工程领域的多灾害概念进行了梳理并建立2个领域间的多灾害概念联系,分析我国不同区域多灾害类型的分布情况,总结归纳工程领域多灾害模型的建立方法,论述不同灾害及灾害组合作用下的工程结构分析方法。最后,阐述工程结构抗多灾风险评估与设计方法的研究进展,为进一步开展工程结构的抗多灾研究提供参考。
China is one of the countries suffering from the most serious natural disasters in the world.The types of hazards are diverse and widely distributed.In some areas,multiple hazards are concentratedly distributed.Various hazards have brought huge threats to the safety of engineering structures in the region.In order to promote the development of the multi-hazard design theory of engineering structures in China,a systematic review of current research status of multi-hazards in the fields of building structures and bridge engineering at home and abroad is carried out.The multi-hazard concepts in the field of disaster science and engineering are sorted out and the connection between the two fields of multi-hazard concepts is established,the distribution of multi-hazard types in different regions of China is analyzed,and the method of establishing multi-hazard models in engineering is summarized.The analysis methods of engineering structures under the action of different hazards and hazard combinations are discussed.Finally,the research progress of the multi-hazard risk assessment and design methods of engineering structures is expounded,which provides a reference for further research on the multi-hazard resistance of engineering structures.
