摘要
由于需要在城市快速路上开设临时施工道口的工程项目越来越多,因此需对施工开口进行详细研究,以保障城市快速路交通的畅通运行。针对快速路施工开口主要的"八""X""∞"3种型式,分析每种型式对城市快速路通行能力、交通安全的影响和适应的地形条件,给出通行能力影响的计算方法和安全保障对策,为以后的快速路施工开口提供参考。
Since the projects requiring setup of temporary construction crossings on urban expressways are more and more, the construction opening should be studied in detail so as to guarantee smooth operation of the traffic of urban expressways. Aiming at principal ＂八＂, ＂X＂ and ＂∞ ＂ types of construction openings on expressways, this paper analyzes influences of each type on traffic capacity and traffic safety of urban expressways and applicable topographic conditions, and presents computing methods for influences on traf- fic capacity and security countermeasures, providing a reference for construction openings of expressways in the future.
