高等级公路中虚交曲线非常普遍,由于受地形的限制,实际工作中虚交的现象是千变万化的,本文讨论了特殊虚交曲线中虚交点的偏角和偏向及里程的计算,然后通过一个实例说明其应用。
Due to the limitation of the terrain, the phenomena of imaginary cross in actual work are varied. This paper discusses the calculation of the declination and deflection of the imaginary cross point in the special imaginary curve and the calculation of the mileage. Example shows its application.
