山区低等级改扩建公路线形设计探究

摘要

在对当前山区低等级改扩建公路线形设计存在的问题分析的基础之上，从平、纵面及其组合上，论述了改扩建公路线形设计要点，简述了线形设计中的灵活性设计，为今后的同类设计提供借鉴与参考。%Based on the analysis of the problem in the current low-grade mountain road reconstruction,from the horizontal,the vertical and the combination,discourses the alignment design of low-grade mountain road reconstruction,elaborates the flexible design. It can offer references for similar design in the future.
