随着中心城区内车流、人流剧增,城市的拥堵问题日益严峻,各地都在大力兴建市政交通工程,通过完善城市路网节点功能,努力提升道路通行能力。城市立交桥建设作为推进城市发展的重要交通工程,不仅有利于改善城市交通环境,更有利于城市综合竞争力及城市品位的提升。作为大型公益性的市政工程,立交桥项目具有社会影响大、投资额大、技术难度高等特点,项目建设不仅带来各种各样的效益,也会带来一些影响和风险,特别是环境影响风险。本文以南宁市五象大道—友谊路立交工程项目为例,对市政立交项目的环境影响风险及其预防对策进行探讨。
With the rapid growth of traffic flow and population in the downtown area, congestion problems in the cities are becoming more and more serious. Various municipalities are vigorously constructing municipal traffic projects and endeavoring to enhance the capacity of roads by improving the functions of urban road network nodes. As an important transportation project to promote urban development, the construction of urban overpass not only helps to improve urban traffic environment, but also benefits the overall competitiveness of the city and the enhancement of urban taste. As a large-scale public welfare municipal project, the overpass project has the characteristics of large social impact, large investment amount and high technical difficulty. The project construction not only brings various benefits, but also brings some impacts and risks, especially the environmental impact risk . This paper takes Nanning Wuxiang Avenue - Youyi Road Interchange project as an example to discuss the environmental impact and its prevention countermeasures of the municipal overpass project.
