摘　　要：秦岭北坡所处位置构造复杂,各类地质灾害时有发生。本文以西安市鄠邑区邬桑峪危岩崩塌地质灾害为例,调查其地形地貌、岩石岩性、构造等特征,详细分析该崩塌灾害的形成机制和危害范围。通过公式计算和赤平极射投影分析崩塌灾害的稳定性,采用Rocfall崩塌落石模拟分析危岩体的运动特征。根据分析结果提出治理方案,可为秦岭北坡同类危岩崩塌提供借鉴。The north slope of Qinling Mountains lies in a complex tectonic place with various geological disasters occurring from time to time.Taking the dangerous rock collapse occurring in Wusangyu of Huyi District in Xi'an as an example,this paper investigates its landform,rock lithology,structure and other characteristics,and analyzes in detail the formation mechanism and damage scope of the collapse disaster,in which the stability of the collapse disaster is analyzed by formula calculation and stereographic projection,and the the movement characteristics of dangerous rock mass were analyzed by rockfall simulation.Based on the analysis results,the treatment plan is put forward,which can provide reference for prevention of similar dangerous rock collapse on the north slope of Qinling Mountains.
