海原大地震诱发黄土滑坡研究现状及展望
Research Status and Prospect of the Loess Seismic Landslide Induced by Haiyuan Earthquake

1920年海原大地震在陇西地区诱发了大量的黄土地震滑坡，造成了惨重的人员伤亡和生态破坏，至今为止，黄土地震滑坡仍是陇西地区典型的地震地质灾害，数量多、灾害重，严重制约着陇西地区的工程建设和经济发展。多年来，我国广大科技工作者就海原大地震及其诱发的黄土地震滑坡开展了大量的研究工作，取得了丰富的成果。本文通过总结前人研究成果，对海原大地震诱发黄土地震滑坡的研究现状进行了总结和评述，梳理讨论了黄土工程特性的研究成果，归纳总结了黄土滑坡的分类，总结分析了海原大地震诱发黄土滑坡的分布规律、影响因素及发育机理，并对今后黄土地震滑坡需要研究的若干问题进行了讨论。通过本文的工作，期以对黄土地震滑坡的研究及陇西地区的工程建设能有一定的参考意义。
The 1920 Haiyuan earthquake had coursed a lot of group nature loess seismic landslides in Longxi area. The landslides caused heavy casualties and serious ecological damage. Because of its large quantity and severe disaster, it seriously restricted the construction and economic de- velopment in the Longxi area. For years, general scientific and technological workers in our country have carried out a lot of research work on the Haiyuan earthquake and the loess seismic landslide induced by it, and have achieved a lot of results. This paper has summarized and reviewed the research status of this field, which introduced the Haiyuan earthquake, tasted the progress of loess engineering properties, summarized the classification of loess seismic landslide, concluded the contributing factor of distribution regularities and developmental mechanism of loess landslide, and discussed some questions that need to be studied from now on in this field. According to the work of this paper, we hope that could put some certain reference for the study of loess seismic landslide and the engineering construction in Longxi area.
