随着我们经济的突飞猛进,交通压力也在不断的增大,不论是在城市道路还是在高速公路上,堵车现象日益严重。公路交通设施的允许交通量在不断的被突破的同时,很多公路的路面结构被破坏、公路等级不够、公路路幅宽度过于狭窄,严重阻碍交通,这在国道与省道的公路中表现的尤为突出,因此就需要对这些道路进行加宽升级改造。本文以某道路K231+070-K268+050加宽改造工程为例,分析了旧路加宽改造相关技术问题。
As our economy progresses by leaps and bounds, the traffic pressure is also on the rise. Traffic congestion is worsening both in urban and on the freeway. While the permissible traffic volume of road traffic facilities is continuously being exceeded, the pavement structure of many roads is damaged, the grade of roads is not enough, the width of road roads is too narrow, and the traffic is seriously hindered. This is especially true in the national highways and provincial highways Therefore, it is necessary to broaden and upgrade these roads. In this paper, a road K231 +070-K268 +050 widening renovation project as an example, the analysis of the old road widening technical issues related to transformation.
