Abstract：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.
