集镇区域国省干线公路改扩建工程技术要点分析

Analysis of Technical Points for the Reconstruction and Expansion of National and Provincial Trunk Highways in Market Town Areas

随着我国城镇化进程的加速,普通国省干线公路穿越集镇区域的情况将越来越多的出现在日常设计工作中。集镇区域国省干线公路路况复杂,沿线建筑物密集,地下构造物混乱,在改扩建工程中需要考虑平衡的因素众多,本文结合集镇区域国省干线公路改扩建工程的设计实例,对相关的技术要点做一些总结,以供同类项目参考。

With the acceleration of urbanization in China,the situation of ordinary national and provincial trunk highways crossing market town areas will increasingly appear in daily design work.The road conditions of the national and provincial trunk highways in the market town areas are complex,with dense buildings and chaotic underground structures along the route.There are many factors that need to be considered for balance in the renovation and expansion projects.This article summarizes the relevant technical points based on the design examples of the national and provincial trunk road renovation and expansion projects in the market town area,for reference by similar projects.
