视距约束下高架快速路圆曲线最小半径计算方法及应用

摘要:

本文以高架快速路为例,通过简化计算模型,揭示了曲线半径与视距、横净距之间的逻辑关系,提出了基于视距约束下最小圆曲线半径的计算方法。

Abstract:

This paper reveals the logical relationship between the minimum radius , stop sight distance and horizontal sight offsets for viaducts’ horizontal design, demonstrates a simplified model and method to calculate the minimum radius by using a certain stop sight distance and horizontal sight offset.
