缓和曲线边线的计算与测设

Calculation and determination for the boundary line of transaction curve

讨论了缓和曲线边线的性质,证实了为保持路线的等宽性,用缓和曲线的平行线作为路线内外侧边线的正确性。推导出缓和曲线边线参数及长度计算公式,为高等级公路路线设计与测设提供了计算公式。

The boundary line's property of transaction curve is discussed. In order not to change the width of the road, it's reasonable to use the parallel lines of tnansaction curve as the inner and outer boundary lines. The calculation formulas of boundary line parameters and length are derived, providing theoretical support for higher grade highway design and determination.
