摘要
道路工程设计过程中经常遇到因道路红线两侧有现状建筑物或是两侧地块已经出让,道路红线范围不能更改的情况。当道路路线不满足规范要求,则需进行道路路线优化,优化后的道路中线偏离也将影响道路平面总体布置。通过分析道路红线受限的多种因素,论述红线各种受限情况下对道路路线的优化方案,结合工程实例着重介绍了各方案的实施过程及优缺点。最后综合研究分析不同的优化方案对道路设计附属专业的影响,以期为日后类似情况下的平面优化提供参考。
This kind of situation is often encountered in the process of road engineering design,because there are existing buildings on both sides of the road red line or the land on both sides has been sold,street boundary line cannot be changed.If the road alignment does not meet the requirements of the specification,it is necessary to optimize the road alignment,and the optimized road alignment will inevitably deviate,and then affect the plane layout.This paper analyzes the various factors of the limitation of street boundary line,and then discusses the optimization scheme of road alignment under all kinds of restrictions of street boundary line.Combined with engineering examples,the implementation process of each scheme and the advantages and disadvantages of each scheme are introduced.Through the research and analysis of the impact of different optimization schemes on road design and other professions,in order to provide reference for plane optimization in similar situations in the future.
