山区城市道路关键节点段设计方案比选的重要性

The Importance of Design Scheme Comparison and Selection of Key Node Section of Urban Road in Mountainous Area

山区城市道賂在设计过程中,应对关键节点段提出合理的方案,从技术、经济、建设期、土地的开发利用价值等多方案进行比选,做到经济合理、方案可行、措施得当,从而提升设计的专业水平和可再生资源的利用价值,因此设计方案比选尤为重要。本文以印江县岩底片区玉屏路为例,从3个不同的方案进行综合比选,详细分析山区的地形地貌,收集相关的地质水文资料,梳理道胳设计的控制条件,通过对道路平、纵、横设计要件,综合考虑道略交通功能和服务水平,选用经济合理的技术指标,达到道路功能完备、交通安全有保障,满足项目的可实施性、可操作性,进一步提升城市交通功能。

In the design process of urban roads in mountainous areas,reasonable schemes should be put forward for key node sections,and multiple schemes form technology,economy,construction period,land exploitation and utilization value should be compared and selected to achieve economic rationality,scheme feasibility and proper measures,in order to improve the professional level of design and the utilization value of renewable resources.Therefore,the comparison and selection of design schemes is particularly important.Taking Yuping Road in Yandi District of Yinjiang County as an example,this paper makes a comprehensive comparison and selection from three different schemes,analyzes the topography of mountainous area in detail,collects relevant geological and hydro-logical data,combs the control conditions of road design,through the horizontal,vertical and horizontal design elements of the road,comprehensively considering the road traffic function and service level,and selecting economic and reasonable technical indicators,to achieve complete road functions,guaranteed traffic safety,and meet the implementation and operability of the project and further improve the urban traffic function.
