摘　　要：预应力技术是解决混凝土构件受力后挠度过大的有效手段,在建筑工程、桥梁工程以及城市轨道交通高架车站中得到了广泛应用。以南京宁天城际轨道交通一期工程S8线高架侧式车站为背景,通过横向盖梁预应力筋设计,对盖梁中预应力筋设计、施工等应注意的问题进行探讨。Prestressed technology is an effective means to solve the problem of excessive defl ection of concrete member under forces,and it has been widely used in building construction,bridge engineering and elevated transit station.Taking S8line elevated side platform station of NanjingNingtian intercity railway project Phase I as an example,with the design of transverse cover beam prestressed tendon,this paper discusses the problems which should be paid attention to duringdesign and construction of the prestressed tendon in cover beam.
