Development of a Monitoring and Warning System for Slope Retaining System

Abstract

This study uses IoT-based sensing modules integrated with the numerical analysis dealing with coupled hydro-mechanical phenomena on soil-structure interactions to develop an innovative cloud warning system on highway slope retaining systems Comparing with traditional monitoring the new IoT-based system is superior in terms of energy consumption hardware cost installation convenience and real-time updating Current practice in slope retaining system is mainly based on empirical basis due to the simplicity For critical sites the accuracy and reliability might not meet the demand This study used numerical tools based on rigorous hydraulic and mechanical analyses to conduct stability analysis on slope retaining systems Both potential failures triggered by ground water rising and surface infiltration within unsaturated zone are considered Consequently the ground water level and water contents are two mainly properties for warning The failure process of retaining systems by different failure mechanisms are simulated to subjectively determine the warning values in different failure cases Because both rigorous analyses and real-time monitoring on triggering properties are considered the proposed warning framework can potentially enhance the reliability of the warning on slope retaining systems
