摘要
结合地震滑坡的特点和相关文献研究,介绍了地震力的分析方法、地震滑坡的机理、地震危险性分析的方法、地震活动性参数的确定方法以及场点地震危险性概率计算原则。将两种地震诱发滑坡预测结果进行对比,分析结果表明,地震滑坡危险区主要集中在中国西部地区(川、滇、甘、陕、新疆等省区)及中国台湾地区,随预测年限的增加场地的地震滑坡危险性也随之增高,地震崩塌滑坡的危险区域明显加大。
United the characteristic of earthquake landslide and the related literature research, this paper introduced the analysis method of seismic force and the mechanism of earthquake landslide, the analysis method of earthquake danger, the definite method of seismicity parameter and the probability computation principle of field earthquake danger. Contrasting these two prediction results of landslide caused earthquake, the analysis result showed that the dangerous area of earthquake landslide concentrates mainly in the west （Some provinces such as Sichuan, Yunnan, Gansu, Shaanxi and Xinjiang and so on） and Taiwan Region. With prediction age increasing, the danger of field earthquake landslide increased. And the dangerous region of earthquake avalanche and landslide enlarged obviously.
