地下快速路正成为国内外城市交通建设的一个发展热点。本文通过对比地面、高架、地下三种快速路系统型式各自优势和适用条件,阐明地下快速路交通系统在构建节能、环保的交通系统方面具有良好的应用前景。从地下快速路节能型结构设计、通风智能控制技术、照明节能技术、节能型路面材料和废气尘埃回收技术等方面进行了节能措施分析。结合低碳设计理念,从设计和建设角度,对地下快速路可能的具体节能措施进行了分析论述,初步探讨了地下快速路交通系统的低碳型设计思路以及未来应重点研究的领域。
Underground expressway is becoming a hot spot for urban traffic construction at home and abroad. In this paper, by comparing the respective advantages and applicable conditions of three types of expressway system, such as terrestrial, overhead and underground, this paper shows that the expressway traffic system has a good prospect in building energy-saving and environment-friendly traffic system. The energy saving measures are analyzed from energy-saving structure design of underground expressway, intelligent ventilation control technology, energy-saving lighting technology, energy-saving pavement materials and exhaust gas recovery technology. Combining the concept of low-carbon design, the specific energy-saving measures of underground expressway are analyzed and discussed in terms of design and construction. The low-carbon design of underground expressway traffic system and the key research fields in the future are preliminarily discussed.
