摘　　要：在现场调查、测量的基础上,对危岩体的分布、规模、形态、分区分带等特征进行了分析,并对危岩地质灾害的成因机制开展研究。分析成果表明:研究区薄厚相间的结构特征、高陡地形下的强卸荷作用、结构面相互切割及组合特点和地震及降雨等外部促发因素是危岩体形成和发展的主控条件。Based on the field investigation and measurement, the characteristics of potentially unstable rock mass were analyzed, such as size, morphology, distribution and so on. Meanwhile, the research to the formation mechanism of the potentially unstable rock mass was carried out. according to the survey findings, it was find that the rock mass structure characteristics with the thick replaces the thin, the high and steep terrain under the strong unloading function, the structure plane cutting and combination characteristics, earthquake and rainfall external precipitating factor are the main control conditions for the rock formation and development.
