长沙南至机场中低速磁悬浮工程限界研究

Research on Changsha Medium and Low Speed Maglev Gauges

为合理制定土建工程断面尺寸,保障行车安全,对长沙南至机场中低速磁悬浮工程限界设计进行深入研究。长沙南至机场中低速磁悬浮工程将限界划分为车辆限界、设备限界和建筑限界。从车辆、线路和轨道相关技术参数入手,详细阐述车辆限界、设备限界的计算因素和计算结果,并给出详尽的典型地段建筑限界图。长沙南至机场中低速磁悬浮工程已按期试运营,经实践检验,其限界设计安全、经济、合理,为后续同类工程提供强有力的技术支撑。

In order to obtain reasonable cross-section dimensions of the civil engineering and ensure the traffic safety,this paper conducts a deep research on the gauges of Changsha medium and low speed maglev project,which are defined as vehicle gauge,equipment gauge and structure gauge,and expounds the calculation factors and results for vehicle gauge and equipment gauge in terms of relative technical parameters of the vehicle,line and track. Meantime,detailed structure gauge charts of typical sections are presented. Presently,the Changsha medium and low speed maglev project has come to trial operation as scheduled and the practical tests show that the gauges designed are safe,reasonable and economical,which provides a strong technical support for the following similar projects.
