Comprehensive monitoring analysis of typical slope along Tianba Highway with air-ground coordination
A single monitoring technique cannot comprehensively monitor the slope deformation along highway,and thus cannot effectively explore the full-cycle deformation laws of these slopes.In this paper,an air-ground collaborative monitoring method for the slope along highway combined with InSAR,micro-variable radar and GNSS is proposed,and a typical slope along Tianba Highway in Guangxi Province is taken as an example for monitoring and analysis.The results show that InSAR technology can capture the accelerated deformation signal before the slip of the slope.In the slip stage,both the micro-variant radar and GNSS can monitor the deformation with the same magnitude,in the later stage of slip,the deformation trends obtained by InSAR and GNSS are basically same with each other,indicating that the slope has changed from the previous significant deformation to a sTab.slight deformation.The combined application of the three technologies can make up for the shortcomings of a single technology to the greatest extent,monitoring the deformation of the slopes along highway more comprehensively and effectively.At the same time,the research results can provide a reference example for the future comprehensive monitoring of slope deformation along highway.
