Abstract: The slope monitoring results are affected by many factors such as monitoring accuracy and human data collection error. These adverse factors might result in the actual slope deformation information could not be obtained in a single monitoring method, and the slope stability state cannot therefore be accurately justified. This paper presents a case history of an expressway embankment slope in Shiyan of Hubei Province. Several different automatic monitoring methods including automatic video surveillance, automatic crack monitoring, surface displacement automatic monitoring and deep displacement automatic monitoring for the slope were used in the target slopes for the deformation characteristics. The stability of the slope was evaluated comprehensively by the coupling and comparison analysis of the monitoring data in the real time dimension based on the analysis of different automatic monitoring data, combined with artificial inspection. The results show that the entire embankment slope was in a stable state, and there is a local surficial deformation near the top of the slope.
