摘要:
针对中低速磁浮车辆需要“抱轨”运行、轨道梁上逃生通道设置困难等问题，详细介绍了长沙磁浮快线高架桥梁多功能疏散平台设计方案。从缩短线间距、降低工程造价等方面，提出了基于疏散平台设置于轨道梁之间、轨面以下的优化方案，以及疏散平台布置于U型主梁上翼缘的优化方案，并对三种设计方案进行了综合比选分析。研究表明：多功能疏散平台优化方案检修工作面大、结构工程量少、美观性好、工程造价低，具有良好的经济适用性。
Abstracts:
In view of the “holding track” running and the difficult setting of escape passage on the track beam problems for medium and low speed maglev vehicle, the design scheme of multifunctional evacuation platform for Changsha Maglev Express Line viaduct is introduced in detail. From aspects of shortening the distance between lines and reducing the engineering cost, the improved schemes of evacuation platform being set between the track beams, below the track surface, and at the upper flange of the U-shaped main beam are proposed, then comprehensively compared and analyzed. The research shows that the improved schemes of multifunctional evacuation platform have obvious advantages in large overhaul face, less structural engineering, good aesthetics, low cost and good economic applicability.
