城市快速路产生于20世纪大规模的城市化运动时期,它是一种具备多车道、控制进出口、中央隔离带、全立体式交叉的道路,是提高城市道路通行能力,缓解城市交通压力的重要交通干道类型,对于强化城市区域间的交通起着关键性作用。成都市在“十二五”期间,规划建设“3环16射”共290.5km的快速路网,以有效解决当前的交通问题,有系统、有步骤地为城市发展预留空间。在快速路网建设中,规划建设中的“两快两射两环”是成都市2012年开工的一号重大工程,其中以成都市二环快速路的景观设计较为成功,为成都市景观规划增添了一道亮丽的风景线。基于此点,本文在探讨城市快速路景观设计要求的基础上,以成都市二环快速路的景观设计为例,分析快速路景观设计应遵循的原则。
The urban expressway originated from the period of large-scale urbanization movement in the 20th century. It is a kind of road with multi-lane, controlled import and export, central isolation zone and all-dimensional intersection, which is to improve the capacity of urban roads and relieve the pressure of urban traffic Important types of traffic routes play a key role in enhancing traffic between urban areas. During the “Twelfth Five-year Plan” period, Chengdu planned to construct a highway network of 290.5km with “3 rings and 16 shots” in order to effectively solve the current traffic problems and reserve space for urban development in a systematic and step-by-step manner . In the construction of expressway network, the planning and construction of “two fast and two shots” is one of the major projects started in Chengdu in 2012. Among them, the landscape design of Chengdu Second Ring Expressway is more successful and Chengdu City Landscape planning adds a beautiful landscape. Based on this point, based on the discussion of the design requirements of urban expressway landscape, taking the landscape design of Chengdu Second Ring Expressway as an example, this paper analyzes the principles that the expressway landscape design should follow.
