Research on Safety Risk Assessment of Highway Slope in Operation
Based on the fact that Guizhou has entered a cyclical peak period of highway maintenance and the large number of slopes on operating highways in mountainous areas,with the increase of highway service time,the safety risks of highway slopes have become increasingly prominent,and risk management is difficult.Therefore,it is particularly important to conduct risk assessment on operating highway slopes.In the paper,based on the needs and reality of slope risk management for operating highways in Guizhou Province,research has been conducted on the slope risk assessment system,risk grading standards,risk disposal principles and so on.Evaluation indicators suitable for slope risk assessment of highways in Guizhou Province are proposed,and the research results have been applied to an expressway in mountainous area in Guizhou to verify the operability of the evaluation system and the reliability of the evaluation results,which can provide reference for similar projects in other regions.
