国内外导标工程设计参数对比分析

Comparative analysis on design parameters of domestic and foreign leading line engineering

为了推进中国标准国际化,推动“一带一路”建设,介绍国内、外导标工程设计计算参数及性能评估方法,从计算原理、资料分析等方面对比国内外规范中关键参数的取值差异,对导标轴线、垂直张角、偏离量及评估方法进行细化分解,得出国内外规范使用的差异及不足。同时结合工程实例,计算中外规范导标的设计参数,并进行对比分析。结果表明,中外导标设计规范的设计原理基本一致,但在垂直张角、水平偏离量及导标效能评估取值上存在一些差异。

In order to promote the internationalization of Chinese standards and The Belt and Road construction, we introduce the design calculation parameters and performance evaluation method of the leading line in domestic and foreign engineering, compare the value differences of key parameters in domestic and foreign codes from the perspectives of calculation principle, data analysis, refine and decompose the guide axis, vertical opening angle, off-axis distance and evaluation method, and obtain the differences and disadvantages of domestic and foreign codes, and compare and analyze the design parameters of the engineering example calculated by domestic and foreign codes. The results show that the design principles of domestic and foreign codes are basically the same, but there are some differences in value of the vertical opening angle, horizontal off-axis distance and effectiveness evaluation of leading line.
