摘　　要：通过分析礐石大桥的病害特点,有针对性地提出了SMA+STC铺装方案,并对该方案的性能优势和经济优势进行分析,与其它几种方案相比,SMA+STC铺装方案能较好地改善因面板刚度等原因引起的钢桥面铺装层病害。通过有限元软件建立全桥及局布模型,验证了该方案安全可行,模型计算结果表明,SMA+STC方案适用于礐石大桥。The SMA ＋ STC pavement scheme is put forward specifically by analyzing the characteristics of disease of Queshi Bridge, and the performance advantage and economic advantage of this scheme and that of other several schemes are compared. The disease of steel bridge deck pavement layer caused by panel stiffness and so on can be improved better through the SMA ＋ STC pavement scheme. The full - bridge and layout models are built by the finite element software, and the safety and feasibility of this scheme are verified. The model calculation results show that, the SMA ＋ STC scheme can be appropriate for Queshi Bridge well.
