摘　　要：通过调查研究省道S233线焦作方庄段内地质环境条件和所发育危岩体特征,共发现危岩体37处.根据危岩体形成的主控因素,研究区危岩体划分为3段:第一段主控因素为断层;第二段为重力卸荷和人类活动;第三段为两组节理的风化和人类活动.在此基础上,运用模糊综合判定的方法对研究区危岩进行了稳定性和危险性评价,并根据3段内危岩体各自的特征提出了相应的治理方案.The study on the geological environments and the features of perilous rocks shows that 37 dangerous rock bodies are found along the Fangzhuang section of Road S233 in Jiaozuo city.The perilous rocks in the study area can be divided into three types according to their controlling factors：the first type was formed by faults,the second one was the result of gravity caving and human activities,and the third one was caused by the weathering of two sets of joints and human activities.On the basis of above sudy,this paper evaluates the stability and dangerousness of perilous rocks by using the fuzzy comprehensive decision method and puts forward their respective control schemes for defferent types of perilous rocks.
