摘　　要：为评价研究区崩塌灾害危险性,文本对区内断层及岩体结构面产状进行了测量与统计,运用赤平投影法分析了调查点的岩体稳定性,鉴别出6个崩塌灾害点,根据灾害点结构面组合特征及不稳定组合数量,将崩塌灾害的危险性等级从高到低依次划分为Ⅰ、Ⅱ、Ⅲ级,结合崩塌灾害点的分布特征及其危险性等级,划分出了Ⅰ-Ⅲ级崩塌灾害危险区。In order to evaluate the risk of collapse disaster in the study area,the occurrence of faults and structural planes of rock mass in the area is measured and counted.The rock mass stability of the survey points is analyzed by using the stereographic projection method,and six collapse disaster points are identified.According to the combination characteristics of structural planes of disaster points and the number of unstable combinations,the risk level of collapse disaster is divided into grade Ⅰ,Ⅱ and Ⅲ from high to low,according to the distribution characteristics and risk grade of collapse disaster points,the risk area of collapse disaster of grade Ⅰ-Ⅲ is divided.
