公路路线纵断面设计方法的探讨

Study of the Design Method of Longitudinal Section of Highway

本文提出以路面中线设计标高作为纵断面设计高进行拉坡，而为适于计算机辅助设计在路线设计中的应用，拉坡后通过标高换算，以路基边缘设计标高作为最终纵断面设计高的纵断面设计方法。

o fit the application of Computer Aided Design in highway route alignment, a method was proposed, by which the elevation of center line is chosen as the design elevation during gradient alignment. After gradient alignment, elevation convertion is made to obtain the final design with the elevation of the edge of pavement as the design elevation.
