摘要
我国目前的公路路线设计采用设计速度理论,设计速度是个定值,而多年的实践表明,车辆实际的运行速度总是随公路线形等条件的改变而变化,所以设计速度理论本身存在一定的局限性,需要采用动态的运行速度对公路的路线设计进行安全性检验,以确保行车安全。文章结合设计实例,探讨公路路线设计中运行速度理论检验的方法。
Currently,the highway alignment design in China adopts designed speed theory.Designed speed is a constant value.However,long term practice shows that the actual running speed of vehicle always varies with the change of highway alignment.Therefore the designed speed theory itself has some limitations.It needs to use the dynamic running speed to verify highway alignment design for safety,so as to ensure driving safety.Based on the actual design practices,the Paper studies the running speed theory inspection method for highway alignment design.
