公路路基设计高度的探讨

研究目的：公路路基的设计高度对公路路基的修建难度、其它构造物的修建要求、对公路的整体使用性能、工程造价都有非常重要的影响。本文特对此进行探讨。研究方法：对不同地区的公路路基高度的设计情况进行分析,并对路基高度合理设计的方法和应注意的问题进行了研究和探讨。研究结果：通过对不同地区公路路基设计特点的分析,提出了关于路基合理设计高度的建议,并结合设计经验,从不同角度提出了一些改善路基设计高度的措施。研究结论：（1）对于山区公路,在保证通常对路基要求的基础上,还应注重新设计理念对环保的要求;（2）对于平原地区公路,应通过各种措施尽可能地减小路基高度;（3）对于软土地区,应当特别注意软基沉降对于路基设计高度的影响。

Exploration on the Height of Design for Highway Subgrade

Research purposes:The height of Highway subgrade affects not only the difficulty of construction for other structure and itself,but also affects the function and cost of the whole project.Research methods:The paper analyses the design condition of varied area,and list out the issues should be noticed when design of the highway subgrade.According to these analyses,the author gives some research and consideration to all these issues.Research results:According the analysis of the design of highway subgrade of varied area,the author puts forward advises about the suitable height of highway subgrade.And according the experience of design,the author also puts forward some methods to improve the design of height of highway subgrade.Research conclusions:(1) At mountain area,on the basis of the formal require to the highway subgrade,we must lay emphasis on environmental protection;(2) At flat country,we should do our best to lower the height of the embankment;(3) At weak soil area,we should pay attention to the influence of sedimentation.
