The study encompasses geotechnical evaluation in the Aravalli-Delhi fold belt. Slope mass rating (SMR) technique and Continuous slope mass rating (CoSMR) have been applied to assess the stability of road cut slopes along NH-58 from Ajmer to Pushkar. The studied five slopes are vulnerable to planar failure, which is further validated by kinematic analysis. Subsequently, the SMR values indicate three slopes are in unstable condition. In addition, to assure more robustness in results, the stability of all slopes was further evaluated by employing a design chart-based technique, Slope stability rating (SSR). As per SSR outcomes, stable slope angles range between 50° and 70° to achieve 1.5 factor of safety. Kinematic analysis-based factor of safety was also determined using pertinent geotechnical parameters. Findings obtained from different methods shows good agreement with each other.

摘要

The study encompasses geotechnical evaluation in the Aravalli-Delhi fold belt. Slope mass rating (SMR) technique and Continuous slope mass rating (CoSMR) have been applied to assess the stability of road cut slopes along NH-58 from Ajmer to Pushkar. The studied five slopes are vulnerable to planar failure, which is further validated by kinematic analysis. Subsequently, the SMR values indicate three slopes are in unstable condition. In addition, to assure more robustness in results, the stability of all slopes was further evaluated by employing a design chart-based technique, Slope stability rating (SSR). As per SSR outcomes, stable slope angles range between 50° and 70° to achieve 1.5 factor of safety. Kinematic analysis-based factor of safety was also determined using pertinent geotechnical parameters. Findings obtained from different methods shows good agreement with each other.
