| 摘 要： | 在山区高速公路建设中,因受地形地物限制,将线路敷设在陡坡上的情形较为常见。介绍陡坡上路基的典型断面形式,深入探讨分台式路基的设计方法和设置条件,通过与其他断面形式的对比,指出分台式路基在山区高速公路陡坡上应用的独特优势。结合大量工程实例,进一步验证分台式路基在陡坡上应用的可行性和有效性,提出分台式路基在今后山区高速公路建设中的建议。

| Abstract: | Due to the limitation of terrain and culture on construction of expressways in mountainous areas,it is common to lay out lines on abrupt slope.This paper introduces typical section types of sub-grade on abrupt slope and deeply investigates design methods and setup conditions for stepped sub-grade.Comparing with other section types,the paper points out the unique advantages of stepped sub-grade when applied on abrupt slope of expressways in mountainous areas.The feasibility and effectiveness of stepped sub-grade applied on abrupt slope are further testified in combination with plenty of project examples,and some suggestions on stepped sub-grade in future construction of expressways in mountainous areas are proposed. |
