摘　　要：波形钢腹板组合梁桥因具有“手风琴效应”逐渐成为大跨度桥梁发展的新方向,为研究内衬混凝土参数对波形钢腹板预应力混凝土(Prestressed Concrete,PC)连续刚构桥抗剪性能的影响规律,采用ANSYS软件建立波形钢腹板PC连续刚构桥有限元模型,通过对比实测数据与数值模拟数据验证了该有限元模型的准确性,并分析了内衬混凝土参数对波形钢腹板剪力及承剪比的影响规律,通过研究可知,内衬混凝土长度、厚度、厚度变化率3个参数的适宜取值分别为9.5 m、0.5 m和0.3。相关结论可为大跨度波形钢腹板PC连续刚构桥的设计和施工提供一定参考。The waveform steel web composite beam bridge has gradually become a new direction for the development of large-span bridges because of its accordion effect.In order to study the influence of lining concrete parameters on the shear performance of waveform steel web prestressed concrete(PC)continuous rigid frame bridges,ANSYS software was used to establish a finite element model of waveform steel web PC continuous rigid frame bridges.The accuracy of the model was verified by comparing measured data with numerical simulation data.The influence of lining concrete parameters on the shear force and shear ratio was studied.The research results indicate that the appropriate values for the length,thickness,and thickness change rate of the inner lining concrete are 9.5 m,0.5 m,and 0.3 respectively.The relevant conclusions can provide reference for the design and construction of large-span corrugated steel web PC continuous rigid frame bridges.
