绿色公路设计中的平纵指标灵活运用探讨

Research on plat and profile linear indicies of green highway design

公路设计过程中路线平纵指标的运用,直接关系到公路的工程规模和行车安全,对于绿色公路理念的落实有着重要影响。文章基于设计规范对指标的具体要求,以及各项指标间的关联,从施工及运营期安全、工程规模控制等角度,对绿色公路设计中平面、纵面各项指标及平纵组合的灵活运用原则,及需要注意的事项,进行了探讨。

The use of plat and profile linear indicies in the process of highway design is directly related to the project scale and driving safety of the highway,and has an important impact on the implementation of the green highway concept.Based on the specific requirements of the design specifications for the indicies and the relationship between the indicies,the article explores the flexible use of the plat and profile linear indicies and the flat and vertical combination in the green highway design from the perspectives of safety during construction and operation and project scale control.Principles and matters needing attention are discussed.
