为满足我国客运专线建设需要,结合我国客运专线路网规划及在建项目研究,主要从工程技术经济及电动车组性能与坡度适应关系两方面,分析研究高速客运专线最大坡度标准的选用原则,提出适合我国国情并与国际高速铁路标准相适应的最大坡度标准。根据电动车组在不同坡度的坡段长度上模拟运行末速度分析提出最大坡度与坡段长度的匹配原则。
In order to meet the need of passenger dedicated line construction in our country and the research on the road network planning and construction projects of passenger dedicated railway line in our country, the principle of selection of the maximum gradient standard for high - speed passenger dedicated railway line is analyzed from two aspects: engineering, technical economy, Put forward the most suitable gradient standard that is suitable for the national conditions of our country and compatible with the international high-speed railway standards. Based on the analysis of the final velocity of the simulated run of the different length of the motor car at different slope, the matching principle of the maximum slope and the length of the slope is proposed.
