交叉口范围内路线转角不设平曲线的条件分析

Analysis on Horizontal Curve Not Set at Corner of Line within Intersection

通过假设的模拟车辆行驶轨迹,采用简单的解析计算,对车辆加宽值、视距、平曲线路段最大横净距、行驶汽车间的安全间隙等进行比较分析,同时对CJJ 193-2012《城市道路路线设计规范》条文6.3.1关于不设置平曲线的执行条件进行了分析和判别,对该条文的进一步理解和使用提出了新的分析思路,供工程规划和设计参考。

Through the assumption of simulating vehicles driving track and using the simple analytical calculation, this paper compares and analyzes the widening value of vehicle, the range of visibility, the maximum cross clear distance at horizontal curve section, and the safety clearance between driving vehicles,analyzes and distinguishes the executing conditions of not setting the horizontal curve stipulated in Clause6.3.1 of Urban Road Line Design Code(CJJ193-2012), and puts forward the new analysis thought for further understanding and using this clause, which can be referred for the planning and design of the similar projects.
