摘　　要：哈大客运专线沈阳站主站房结构采用"建桥合一"的大跨预应力混凝土框架结构体系。针对"地下通道桩基与下部地铁盾构的相互影响"进行了专项论证;站台层列车正线处设置双柱与到发线分离,形成连续刚构桥,有效地减小高速列车通过对上部候车厅层舒适度的影响;商业夹层局部采用大跨钢桁架楼盖,对其竖向加速度对旅客舒适度的影响进行了分析,应用TMD减振技术有效地缓解了结构竖向加速度峰值。屋盖采用67.0m跨桁架拱结构,以实现结构与建筑完美结合。Building-bridge integrated structure in large-span prestressed concrete frame structure system was used for the main station building of Shenyang Station on Harbin-Dalian Passenger Dedicated Line. And then expert evaluation was organized on ＂ the interaction between the underground passage foundation piles and the metro shield tunneling＂. In this structure, double columns were erected at the station platform layer so that the main line of the trains could be separated from the receiving-departure line, forming a continuous rigid frame bridge, which could effectively reduce the influence on the upper waiting hall layer＇s comfort level caused by high-speed train＇s passing through. And, the large-span steel trussed floor system was used for part of the commerce interlayer, for which, the influence on passenger＇s comfort level caused by vertical acceleration was analyzed, and TMD vibration damping technology was adopted so as to relieve the crest value of the vertical acceleration. In addition, steel trussed arch structure with a span of 67.0 meters was used in the roof system so as to achieve the perfect combination between the structure system and the architecture system.
