中欧规范改路主要几何设计指标对比分析

Comparison and Analysis of Main Geometric Design Indicators between China and European Standards for Deviation of Roads

以黑山南北高速公路改路项目为背景,对比分析了中欧规范在改路圆曲线、超高、缓和曲线等主要几何设计指标上的差异。研究表明:欧洲规范在改路的几何设计上,平纵线形指标控制相对宽松,给设计者以更大的操作空间。通过中欧规范在改路主要几何设计指标方面的对比分析,可为东欧地区类似项目提供设计借鉴和研究参考。

Based on the deviation project of the North-South Highway in Montenegro,the differences between the main geometric design indicators,such as the circular curve,superelevation and transition curve in China and Europe are compared and analyzed.The research shows that the European standard controls relatively loose in the deviation design,giving the designer more space.The comparative analysis of the main geometric design indicators of the deviation between the specifications of China and Europe can provide reference for design and studies of similar projects in eastern Europe.
