竖曲线半径选择—平纵线型均衡的定量分析

Selection of Vertical Curve radius-Quantitative Analysis on Horizontal and Vertical Curve Equilibrium

公路路线设计中,平曲线和竖曲线大小要保持均衡,这是路线设计中的核心理念。"高速公路规划与设计"一书239页"平竖曲线均衡的定量指标,并没有一个统一的规定,……"。通过理论推演,给出平曲线和竖曲线大小保持均衡的数学表达式。

During highway route design, horizontal curve and vertical curve shall achieve equilibrium which was the core idea of route design. In ＂Highway Planning and Design＂ page 239, it said that ＂There was no uniform standard for horizontal and vertical curve equilibrium quantitative index,...＂. By theoretical deduction, this paper presented the mathematical expression for keeping horizontal curve and vertical curve equilibrium.
