摘要:
地质灾害是目前人类社会发展面临的主要威胁之一,仅2018年全国范围内发生地质灾害高达2966起,直接造成经济损失约14.7亿元。地震滑坡作为地震引起的主要地质灾害之一,不仅存在范围广、数量多,而且危险性高,波及范围极大,易对人类生命及财产安全造成重大损害,所以分析研究地震滑坡成因与机理,建立地震滑坡危险性评价及预测模型变得极为重要。本文通过系统地梳理、回顾了国内外对地震滑坡危险性的研究现状,对目前的地震滑坡危险性相关研究进行总结,分类论述了滑坡危险性预测方法及评价模型,讨论各类方法的优缺点,提出存在的问题与发展方向,为以后更为深入的研究提供参考。Geological disaster is one of the major threats to the development of human society. In 2018, 2966 geological disasters occurred nationwide, causing economic losses about ¥1.47 billion. Earthquake landslide is one of the main geological disasters caused by earthquake, which not only has a wide range and a large number, but also high risks and a wide range of impacts causing significant damage to human life and property safety. So the research on the causes and mechanism of earthquake landslide as well as the seismic landslide hazard evaluation and prediction model is extremely important. This article reviews and summarizes the domestic and foreign research about the risks of seismic landslide hazard, discusses the classification of landslide hazard prediction methods and the evaluation model. Besides, the article discusses the advantages and disadvantages of various methods, proposes the existing problems and development direction, and provides a reference for more in-depth research in the future.
