网页Carbonaceous mudstone and shale (CMS) slopes are prone to disintegration, instability, and other engineering diseases. This calls for a suitable method to evaluate the slope stability and eliminate the hazards. However, the traditional slope monitoring system is slow in alarm and response, and inaccurate in stability analysis.
