摘　　要：河谷地区历年来地震滑坡灾害严重。通过分析典型河谷城市100余个黄土滑坡影响因素的数据,结合前人工作,对滑坡进行了针对性的分类,将河谷城市黄土地震滑坡分为黄土内滑坡、黄土—基岩接触面滑坡以及黄土—基岩滑坡。通过研究针对危险边滑坡防治给出建议,在河谷地区地震黄土斜坡稳定性分析和灾害预测中需要考虑多项影响因素。There are seriously seismic landslide disasters in the valley areas over the years.The influencing factors of more than 100 typical loess landslides are analyzed.By combining the previous work,the landslides in valley cities of loess areas are divided into three types: homogeneous loess landslide,loess-bed rock interface landslide and loess-bed rock landslide.Through the investigation and analysis of earthquake risk,some suggestions are given.Many factors should be considered in the stability and hazard prediction of seismic loess slopes.
