이무한지철4호선이기공정위례，침대현요식강탄황부치판도상재궤도설계시공과정중출현적문제，천술료예제강탄황부치판도상적설계방안급설계시공특점。공정실시결과표명，상비현요부치판도상，예제부치판도상재제고도상적시공효솔、부치판적질량화내구성방면효과량호。
Taking the second phase project of Wuhan metro line 4 as an example, the paper focuses on the problems occurred in process of the design and construction of cast-in-situ steel spring floating slab track, and explains the prefabricated steel spring floating slab design scheme and its design and construction features. The results show that comparing with cast-in-situ lfoating slab, the prefabricated lfoating slab has improved the construction efifciency of ballast bed and lfoating slab quality and durability, so the effect is good.
