| 摘 要： | 黄土滑坡因其危害大、分布广成为近年工程地质研究热点问题。首先对黄土滑坡类型划分进行了讨论，基于滑坡物质组成及主滑面发育位置的黄土滑坡分类方案反映了我国黄土滑坡的主控因素，各类滑坡活动特征明确，建议将其作为黄土滑坡分类的首选方案。对黄土滑坡的发生、滑动机制以及滑坡液化机制进行了评述，并就两类典型液化型黄土滑坡滑动模式、进一步研究思路进行了讨论。对地震诱发黄土滑坡进行了专门的述评。最后，对今后黄土滑坡研究提出了几点设想。

| Abstract: | Loess landslides are widely distributed in China and can have catastrophic consequences,and have therefore become one of hot research topics in engineering geology.In this paper,the present classification schemes of loess landslides were firstly summarized.Since the sliding material and the location of slip surface are most important for a landslide,it is thus suggested that the classification scheme,which can reflect the sliding material and the slip surface,should be used as a basic classification for loess landslide survey.Secondly,the paper discussed landslide initiation and movement mechanisms of the landslides occurring within loess and the landslides occurring at the interface between loess and underlying mudstone.Two typical long-runout loess landslides caused by static liquefaction were taken as examples and their possible pore pressure generation modes were proposed.The paper also briefly reviewed the research progress on earthquake-triggered landslides in loess area.Finally,some thoughts on future research of loess landslides were presented. |
