摘　　要：预应力连续刚构板梁桥在国内的应用和研究较少。这种结构结合了板梁桥和刚构桥的特点,适用于较大联长、较多跨数的中小跨径桥梁结构。由于这种结构拥有较高的超静定次数,施工过程中体系转化次数较多,所以不同施工顺序对该结构的力学性能将会产生明显的影响。依托黑山南北高速公路项目,研究不同施工顺序对预应力连续刚构板梁桥力学性能的影响。研究结果对工程实际实施过程中的工程进度、成本控制有较大帮助,并对这种结构的设计工作具有重要指导意义。Prestressed continuous rigid frame plate girder bridge is less applied and studied in China.This type of bridge structure combines the characteristics of plate girder bridge and rigid frame bridge,suitable for small and medium-sized span bridge structures with longer modular length and multiple spans.Because the structure has a high number of super-static times and more system transformation times during construction,different construction sequences will have a significant impact on the structural mechanical properties.Based on Bar-Boljare Highway Project in Montenegro,in the paper the influence of different construction sequences on the mechanical properties of prestressed continuous rigid plate bridges is studied,which is helpful to the construction progress and cost control in the actual implementation of the project,and has important guiding significance for the design of the structure.
