本文从地质力学和工程地质的观点,结合安徽黟县至太平县公路坚硬裂隙岩体坍滑的实例,概述了岩体失稳的一般特征,对其失稳因素、机制及其发展阶段进行了初步分析、探讨。并对公路勘测、设计、施工及营运中,加强岩体稳定性观测和分析提出具体建议。 Based on the examples of geomechanics and engineering geology, and combining with the examples of the slump of rigid cracked rock mass in highway from Juxian to Taiping County, Anhui Province, the general characteristics of rock mass instability are summarized. The factors of instability of rock mass, mechanism and development stage are summarized Preliminary analysis, discussion. And put forward specific suggestions for strengthening the observation and analysis of the stability of rock mass in the road survey, design, construction and operation.
