| 摘 要： | 六盘山东麓地层结构特殊，断裂褶皱等构造发育，滑坡及其隐患点等不良地质灾害较多，特殊的地理、构造位置和潜在的孕震背景，致使该区具有产生大型滑坡的可能。本文依据新一轮以图幅带专题研究的地质灾害调查获取大量的数据，通过统计分析，对六盘山东麓断裂带滑坡产生的孕灾地质环境条件及其滑坡特性等进行了剖析，将研究区滑坡归纳为红层软岩滑坡、断层影响型滑坡、堆积层滑坡、黄土型滑坡4种不同类型，同时对其形成机理进行了探讨分析与研究，为完成地质灾害风险性区划评价，提出地质灾害综合防治对策建议提供了重要的理论依据。

| Abstract: | The stratigraphic in the eastern Liupanshan is special and the structure like the fault and fold is developed. There are many bad geological disasters such as landslide and hidden danger disaster. Special geographical, structural locations and potential seismogenic background make the area have the possibility of large landslide. Based on the new round of map investigation and evaluation with special subject research of geological hazards in the eastern Liupanshan, large amounts of data were obtained in the fault zone of source district Jing River. Through statistical analysis, geological environmental conditions and landslide characteristics in the fault zone of eastern Liupanshan were analyzed. The landslides in the study area were classified into the red bed soft rock landslide, the fault impacted type, accumulation landslide and loess landslide .The formation mechanism of the landslide were also discussed and analyzed. It provide an important theoretical basis for the evaluation of geological hazard risk zoning, the comprehensive prevention and control countermeasures of geological hazards. |
