论减小山区高速公路的线形指标值以降低工程造价

Reducing Linear Index Value of Mountain Expressway to Bring Down Engineering Cost

目前高速公路设计中,为了保障车辆运行安全,线形指标设计运用的值越来越高,以至于对于山区地形复杂路段造成不必要的工程浪费。鉴于此,提出在采取有效措施满足视距的前提下,采用较小的线形指标,以减小工程量,节约工程投资。

In design of expressway,the value of linear index is becoming higher and higher in order to guarantee vehicle running safety.It has resulted in unnecessary engineering waste on terrain-complex sections of mountain expressways.Given this,it puts forward the method by smaller linear indexes on the premise of taking effective measures to meet the stopping sight distance,which can reduce the amount of project and save project investment.
