Research on Highway Slope Stability Based on Hierarchical Fuzzy Comprehensive Evaluation Method

Abstract

The highway slope stability monitoring based on the Internet of Things technology can effectively realize the accurate and real-time three-dimensional monitoring of highway slopes and reduce the loss caused by road slope disasters. From the perspective of the system, based on the geological structure, topography and hydrology of highway slopes in Guangxi, this study uses the analytic hierarchy process to establish the stability of highway slopes based on the analysis of the characteristics of highway slopes, survey data, and factors affecting stability. This paper analyzes the structural model of the influencing factor layer, calculates the weights of the influencing factors of the road slope stability, combines the fuzzy relationships between the factors, and uses the comprehensive evaluation principle in fuzzy mathematics to realize the evaluation of slope stability. The results of an example analysis show that the evaluation method is reliable and effective.
