摘　　要：为了保证顺层滑坡的有效监测,提升顺层滑坡的监测精度,实时获取风化岩节理边坡顺层滑坡滑动幅度,提出风化岩节理边坡顺层滑坡监测方法。根据风化岩节理边坡顺层滑坡结构特征与失稳模式的分析结果,选择顺层滑坡的监测内容并布设监测点,安装传感器设备,通过实时数据传输与处理,得出顺层滑坡的监测结果,并判断当前监测数据是否启动了预警程序。此研究以某高速公路风化岩节理边坡顺层滑坡为研究对象,结合其地质特征,构建相应的仿真模型,行顺层滑坡监测方法。仿真与实例测试结果表明:该监测方法的平均监测误差低于0.1 mm,监测精度较高,可以以监测数据为基础,计算仿真顺层滑坡样本的量化稳定系数;该风化岩节理边坡顺层滑坡整体处于基本稳定状态。为该领域的相关研究提供理论和实践参考。In order to ensure the effective monitoring of bedding landslides,improve the monitoring accuracy of bedding landslides,and obtain the sliding amplitude of bedding landslides of weathered rock jointed slopes in real time,a monitoring method of bedding landslide of weathered rock jointed slope was proposed.According to the analysis results of structural characteristics and instability mode of bedding landslides of weathered rock jointed slopes,the monitoring content of bedding landslides was selected,and monitoring points were set up.Sensor equipment was installed,and the monitoring results of bedding landslides were obtained through real-time data transmission and processing.In addition,whether the current monitoring data has started the early warning program was judged.Taking the bedding landslide of weathered rock joint slope in a highwayas the research object,combined with its geological characteristics,the corresponding simulation model was constructed,and the monitoring method of bedding landslides was implemented.Simulation and test results show that the average monitoring error of this method is less than 0.1 mm,and the monitoring accuracy is high.The quantized stability coefficient of simulated bedding landslide samples can be calculated based on the monitoring data.The bedding landslide of the weathered rock jointed slope is basically stable.It provides a theoretical and practical reference for related research in this field.
