摘　　要：输电塔-线体系是重要的生命线工程,确保其安全意义重大。近年来,极端天气、自然灾害和安装事故频繁发生,对输电塔-线体系造成严重破坏,引起社会的广泛关注。针对近年来输电线路灾害发生的原因和破坏形式,本文从构件及节点试验、数值分析方法、连续性倒塌研究进展和真型试验四个方面总结分析了现阶段国内外对输电塔-线体系灾变机理的研究成果。通过对问题的归纳与总结,旨在发现研究过程中存在的问题,明确输电塔-线体系灾变机理研究的方向,增强对输电塔-线体系抗倒塌能力的认识,为输电塔的研究和设计提供参考。The transmission tower-line system is one of the most important lifeline projects and its security is extremely significant. In recent years, extreme weather, geological disasters and installation accidents occurred frequently, and as a result, transmission tower-line systems were damaged severely, which received widespread social concerns. According to the disaster causes and failure modes of transmission lines, current research results about disaster mechanism of transmission tower-line system were summarized from four aspects, joint and specimen test, numerical analysis, progressive collapse analysis and full-scale test. Based on the generalization and summation of these problems, it is aimed that the deficiencies in study of transmission tower-line system can be ruled out, the research direction on disaster mechanism of transmission tower-line system can be pointed out, the understanding of collapse resistant capacity of transmission tower-line system can be deepened. This study can provide reference for the study and design of transmission lines.
