我国高速铁路速度目标值问题的研究

THE RESEARCH ON OBJEXTIVE VALUE OF SPEED OF HIGH-SPEED RAILWAY

196 4年日本建成东海道干线时速 2 0 0 km/h的高速客运铁路 ,揭开了世界高速铁路发展的序幕。由于高速技术日趋成熟和它自身所具有的技术经济特征 ,适应了各国经济、社会发展的需要 ,世界各国竞相提高速度、修建高速客运铁路 ,至今已有 10个国家 (日本、法国、英国、美国、意大利、西班牙、荷兰、俄罗斯等 )建成时速 2 0 0 km/h以上的高速铁路。高速铁路的修建和发展标志着世界铁路已进入了向高速发展的新时代。本论文不涉及对高速铁路系统模式优劣的比选 ,仅就对已报国家审批的高中速共线方案的高速铁路中的有关问题进行研究和探讨。本文提出了我国发展高速铁路是当务之急 ,讨论了高速铁路目标值的确定 ,对于高中速共线运行方案下的有关部分参数选取 ,提出了优化方法 ,以期为高速铁路规划和建设作参考 ,为深化研究提供基础条件。

The completion of Tokai new main lines with the speed of 200 km/h in Japan in 1964 uncovered the prelude of the express railway development. Owing to more & economical character. Express railway meet the need of economical and social development In variable Country. so every coutry competes in enhancing speed and constructing express passenger railway. Until now, there are ten countries which have constructed express railway above 200 km/h. The construction and development of express railway Indicate that world railway has entered the highspeed developmental times.This paper is not concerned about the comparison among the express system modes. The issues relate to express railway with the program of high speed and moderate speed in common-line, Which is reported to state to ratified, will be argued.This paper will discuss the definiton on the objective value of express railway speed. It will make a conclusion that it is urgent to develop express railway and will provide optimization method to selection parameters in the program of high speed and moderate speed in common-line. The conclusion in this paper will be references in the railway planning and construction and the basis for further research.
