摘要
结合工程投资,分析了确定速度目标值的主要影响因素,并探讨了速度目标值与正线间距、最小曲线半径、最大坡度之间的关系和选取原则,提出了客运专线主要技术标准的建议设计参考值。
Combined with engineering investment, the main influencing factors of speed target value are analyzed and the relationship between speed target value and main line distance, minimum curve radius and maximum grade and their selection principle are discussed. The recommended design value of the main technical standards for passenger dedicated line is advanced.
