摘　　要：结合辽宁省境内建兴高速公路某高边坡的施工过程,利用现代非接触测量技术采集和分析岩质边坡的结构面信息,在此基础上采用大型三维离散元软件,通过模拟边坡开挖过程中边坡岩体的位移变化来判断边坡岩体是否失稳,同时进行边坡岩体的现场监测,通过监测数据验证数值模拟正确性,为后续数值模拟优化监测方案提供保障,从而为该边坡工程的安全施工提供理论参考和借鉴。Modern non-contact digital measurement technology was used to collect and analyze rock slope structural plane information during the construction process of Jianchang- Xingcheng highway high slope in Liaoning province. On this basis,A large- scale 3D discrete element software was adopted to simulate the displacement of the rock mass during the excavation of the slope,and then the slope was evaluated according to the simulation results. At the same time an on-site monitoring of the rock slope was conducted as the verification measure. According to the comparison,the accuracy of numerical simulation is validated and it can be used in the optimization of subsequent monitoring plan. This prediction method can provide some theoretical reference for the safe construction of the slope engineering.
