摘要
分析了城市地下道路的类型及特点,总结了开展城市地下道路设计的原则和方法,并针对目前建设众多的地下隧道,从道路线形、横断面和安保设施三个方面浅析了地下道路的总体设计要点。特别是路线设计中需要验算平曲线和竖曲线行车视距,对直线段长度和出入洞口设计进行重点关注。
The types and features of underground road are analyzed.The design principles and methods of urban underground road are summarized.Based on the most constructed underground tunnels,the overall design points are elementarily analyzed from three aspects of road alignment,cross section and safety facilities.The horizontal and vertical curves of driving sight distance are required to check and calculate especially in the route design.The straight line length,and the tunnel entrance and exit should be concerned in the design.
