中文摘要: 地震通过改变地表岩体的物理力学性质而使得震区滑坡、泥石流等地质灾害显著增强的现象在震后持续相当长的一段时间。在研究分析国内外学者对地震地质灾害研究成果的基础上,系统总结了目前在地震诱发地质灾害的发育分布规律及其演化趋势方面的研究方法及成果,探讨了研究中存在的问题及薄弱环节,并对未来的研究方向及趋势进行了展望。研究认为目前国内外对地震地质灾害长期活动性的研究还没有形成体系,尚缺乏有效的研究方法与技术,并且研究成果存在较大差异性。地震扰动区地质灾害长期活动性研究可为震后地质灾害的长期防灾减灾和风险管控提供科学支持,也能对地震地质灾害相关问题的进一步深入研究提供参考。

Abstract:Earthquake can significantly change the physical and mechanical properties of surface rock masses, which leads to an obvious geohazard increase after earthquake for a long period of time. Based on the review and analysis of the current research status of long-term activity of post-earthquake geohazard, the current research methods and achievements of development, distribution rule and evolution trend of earthquake-induced geohazard are systematically summarized, the problems and weaknesses during the research process are discussed, and the prospects and the future research directions and trends are presented. At present, there is no perfect research system and effective research methods and techniques for long-term activity of post-earthquake geohazard, and the research results have a big difference. In-depth scientific research on long-term activity of post-earthquake geohazard in seismic-disturbed regions can provide scientific support for long-term disaster prevention, mitigation and risk control of geohazard after the earthquake and also present a reference for further study of this scientific problem.
