为了分析四川省巴中地区某危岩体稳定性,在对其结构特征及变形破坏模式较系统分析基础上,提出了该危岩体稳定性的影响因素,确定了改危岩体的崩塌类型,建立了主断面的工程地质模型,并采用相关公式计算了该危岩体在自然、地震和暴雨3种不同工况下的稳定系数。结果表明自然和地震工况下该危岩体处于稳定状态,但暴雨工况下属于欠稳定。研究结果对该危岩体的防治将提供较可靠的参考依据。
In order to analyze the stability of a dangerous rock mass in the Bazhong area of Sichuan Province, based on a systematic analysis of its structural features and deformation failure modes, the influencing factors of the stability of the rock mass are proposed, and the types of collapse of the rock mass are determined , The engineering geological model of the main section was established and the stability coefficient of the dangerous rock mass under three different conditions of nature, earthquake and rainstorm was calculated by using the correlation formula. The results show that the rock mass is stable under natural and seismic conditions, but it is not stable under heavy rain conditions. The research results will provide more reliable reference for the prevention and treatment of the dangerous rock mass.
