摘要
以某三跨预应力混凝土连续斜交箱梁桥为依托,利用有限元软件ANSYS建立不同斜度的三维实体模型,对其横向应力进行对比分析,得出在施工阶段三跨预应力混凝土连续箱梁桥支点截面和跨中截面的横向应力分布规律,以期为类似问题提供参考。
Based on a prestressed concrete skew box girder continuous bridge with three span, this essay utilizes the ANSYS finite element soft- ware to establish three-dimensional entity models with different slope angles and analyze the transverse stress in different section. The results show the laws of distribution of transverse stress in the support section and mid-span section in the construction stage, which has accumulated valuable experience for similar engineering construction.
