摘要
在汽车动力性能分析和工程经济技术论证的基础上,通过理论分析和现场调查的方法,对比分析现行公路工程技术标准在陕西公路建设中的适用性,提出了陕南秦巴山地和陕北黄土高原地区高速公路和一级公路最大纵坡建议值(4%～6%)不设超高平面最小半径的建议值.研究结果进一步完善了现行公路技术标准,同时为陕西地区的公路设计提供指导依据.
Based on the automotive dynamic virtue and the engineering’s economic and technology characteristics in Shaanxi, the suitability of Chinese current technical standard in Shaanxi was discussed. The largest profile grade parameter of freeway and arterial highway at Qinba mountain area that is in the south of Shaanxi, and the yellow soil plateau that is in the north of Shaanxi should be 4%~5%. The smallest horizontal curve radius of the limited plane were recommended. The conclusions can give a perfection on current technical standard of highway engineering and provide a direction for road design in Shaanxi.
