摘要
1920年海原地区发生的一次8.5级大地震,诱发了大量的滑坡灾害。据野外调查和航片判读资料分析了海原地震滑坡形成的基本条件,探讨了影响海原地震滑坡分布的主要因素。研究结果对滑坡灾害的预测有一定意义。
In 1920, a great earthquake of M 8. 5 occurrence caused a heavy catastrophic landslide.So, based on the field investigation and aerial photograph interpretation, we analyzed the Haiyuan earthquake landslide and its basic condition of formation, the main factors that affected Haiyuan earthquake landslide distribution were approached.The result is of a certain significance in the prediction of landslide hazard.
