摘要
为支撑《市域铁路设计规范》编制,针对市域铁路隧道净空面积取值开展研究。在国内外资料调研基础上,根据现行规范对铁路隧道净空面积的规定,针对市域车辆尺寸及性能、隧道内接触网悬挂方式、建筑限界、防灾疏散等方面要求,确定满足基本使用功能的市域铁路隧道最小净空面积;综合相应舒适度标准下满足空气动力学效应的隧道净空面积计算结果,提出不同速度目标值下市域铁路单、双线隧道经优化后的隧道最小净空面积取值。研究成果为《市域铁路设计规范》隧道章节相关条文的编制提供了纳规依据。
The study on the tunnel inner perimeter of suburban railway is conducted to support the preparation of the Design Specification of Suburban railway. Based on the review of related materials in China and abroad and according to the existing regulations on railway tunnel inner perimeter, the minimum value of the tunnel inner perimeter of suburban railway which can meet the basic use function is determined with fulfillment of such requirements as vehicle size and performance, the OCS setting in tunnel, the structural gauge, disaster prevention and evacuation; By integrating the calculated tunnel inner perimeter values that fulfill the aerodynamic effects under different riding comfort standards, and considering the suburban railway serves as both national railway and urban rail transit, the paper puts forth the minimum inner perimeter values for single and double-track tunnels of suburban railway to meet different speed targets. The research results provide foundations during the preparation of related contents in the ＂Tunnel＂ chapter of the Design Specification of Suburban railway.
