Safety Evaluation of Long and Steep Slope Design Based on Operating Speed Analysis
Safety evaluation for highway projects is a process of comprehensive detection and analysis of the design document from the perspective of safety operation,and it can effectively avoid safety defects,realize essential safety,and reduce hidden dangers of accidents.This paper presented a safety evaluation of a two-way six-lane expressway design document in a mountainous area using the operating speed analysis method to evaluate the coordination of predicted operating speeds.Focusing on the existing continuous long and steep slopes,the temperature of the brake hub of trucks was predicted and analyzed,and corresponding safety improvement measures were proposed,expecting to enhance highway operation safety.
