| 摘 要： | 1995年甘肃省永登发生的5．8级地震，触发了150多处滑坡，为了分析地震区黄土滑坡灾害的成因，通过对地震滑坡区域内黄土的基本物理力学性质和动力特性的试验，研究了黄土的相关性质与易损性关系，并对地震引起黄土滑坡的原因进行了探讨．研究结果表明，黄土易损性与地震黄土滑坡有密切关系．易损性大的黄土，地震引发滑坡灾害严重．

| Abstract: | During the 1995 Yongdeng 5.8 earthquake,more than 150 landslides were triggered.To study the cause of these landslides,the physical,mechanical and dynamic characteristic properties of the loess in the area were studied to reveal the relation between loess landslides and its soil mechanical properties.Through a multi-indices research,it is proved that loess vulnerability has much to do with landslides.The loess with higher vulnerability slides easily under earthquakes. |
