公路交通设施设计要点研究

Research on Key Point of Highway Traffic Facility Design

为保证公路设施适应复杂多变的交通和环境条件,文章阐述了公路交通设施设计原则,根据适用性、可行性及综合性原则,具体论述护栏、标志与标线、视线诱导与隔离设施,以及防眩目设施等交通设施的设计要点,分析其防腐处理方法。研究表明,合理设置交通设施能提高公路的安全性和交通效率,采用热镀锌、粉末喷涂和阴极保护等技术,能有效降低维护成本。

In order to ensure that highway facilities adapt to complex and changeable traffic and environmental conditions,this paper expounds the design principles of highway traffic facilities.According to the principles of applicability,feasibility and comprehensiveness,the key design points of guardrail,sign and marking,sight guidance and isolation facilities,and anti-glare facilities are discussed in detail,and the anti-corrosion treatment methods are analyzed.The research shows that reasonable setting of traffic facilities can improve the safety and traffic efficiency of highways.The use of technologies such as hot dipped galvanizing,powder spraying and cathode protection can effectively reduce maintenance costs.
