中国与澳大利亚公路平面线形设计标准对比

Comparison between China and Australian Highway Specifications on Horizontal Alignment Design

摘要: 目前南太平洋工程市场上，中国规范与主流澳大利亚规范中诸多细节不同，且澳大利亚标准体系与中国标准体系存在大量思路上的不同，分散在各不同的规范文本中。首先梳理了中国规范与澳大利亚规范中关于道路设计中平面设计内容的对比，包括平曲线要素设计以及平曲线组合设计：直线设计类似；关于圆曲线设计的原理相同但各参数及最小圆曲线设计半径不同；缓和曲线的线形不同但曲线性质相同，故设计计算公式也相同。然后，针对中澳规范中平纵组合设计也进行了比较分析。最后，建议中国公司在澳洲南太平洋地区开展实施相关公路工程项目，应该根据具体的情况采用合适的技术规范，特别应注重相较于中国规范的差异性。

Abstract: Currently, in the South Pacific engineering market, there are numerous detailed discrepancies between Chinese specifications and mainstream Australian ones. Moreover, the Australian stan-dards system and the Chinese one display significant differences in their approaches, scattered across various standards documents. This paper presents a comprehensive comparison of the plane design between Chinese and Australian specifications, including the plane curve element design and the plane curve combination design. The results indicated that the design of straight lines is largely the same; the design of circular curves is based on the same principles but the pa-rameters and the minimum radius of the design of circular curves are different; the transition curves are different but the nature of the curves is the same, therefore, both specifications have the same the design calculation formulates. Then, a comparative analysis is also carried out for the plain and longitudinal combination design of the Chinese and Australian specifications. Lastly, a suggestion was proposed that Chinese companies carrying out and implementing relevant road engineering projects in the South Pacific region of Australia should adopt appropriate technical specifications according to specific circumstances, paying special attention to the differences compared with Chinese standards.
