摘　　要：以某大桥32 m预应力混凝土简支箱梁为例,利用ANSYS有限元分析软件建立三维实体模型,进行恒载、活载作用下剪力滞效应分析,得出剪力滞分布规律及变化特点,对类似箱梁设计具有一定的指导作用。Taking 32 m pre-stressed concrete simply-supported box girder in a certain bridge as an example, the author establishes 3D solid modal with ANSYS finite element analysis software, analyzes the shear lag effect under the actions of dead load and live load, and gains the distribution regulation and changing characteristics of shear lag, which has certain guiding functions for the design of similar box girder,

关 键 词：整孔简支箱梁 有限元法 剪力滞
