摘　　要：针对在浮置板轨道结构的施工过程中合理有效地选择施工工法这一难题,重点介绍并对比分析散铺法、预制钢筋笼法、全预制短板浮置板施工和半预制短板浮置板施工这4种浮置板轨道结构的施工工法,通过分析对比得出,半预制短板浮置板施工方法较其他施工工艺简单,适应能力强,施工周期短,施工成本低,特别适合浮置板轨道快速施工。With floating slab track structures being widely used ha urban rai/transit, more and more construction methods appear. How to choose a reasonable and effective construction method in the construction process of floating slab track structure becomes a big problem to engineers. This paper introduces and analyzes the spread method, precast reinforced cage method, whole precast short floating slab construction method and the half floating slab precast short construction method. A contrastive analysis is made among these four floating slab track structures and it is found that floating slab precast short construction method is simpler and more adaptable and requires shorter construction period and lower construction cost. it is especially suitable for rapid construction of floating slab track （FST）.
