| 摘 要： | 为了探讨装配式预应力混凝土斜交空心板桥,在单位荷载作用下的最不利内力值,为斜交空心板的计算提供依据,以某装配式斜交空心板桥为工程背景,采用ANSYS提供的参数化语言APDL,对大桥进行弹性分析,先计算控制截面的弯矩、扭矩、剪力影响面,通过大量计算,得到关键截面的内力影响面。同时探讨装配式斜交空心板桥与整体式斜交空心板桥在受力特性的不同,为装配式预应力混凝土斜交空心板桥的进一步计算提供依据。

| Abstract: | To find out the value of the most unfavorable inner force,which provides references for the calculation of the skew hollow slab,of the assembled prestressed concrete skew hollow slab bridge with the action of unit load,this paper,taking some assembled skew hollow slab bridge as engineering background,does the elastic analysis of this bridge using ANSYS parametric design language(APDL).It first computes the influence surface of the bending moment,the one of the torsional moment and the one of the shearing force of the control section respectively.After a great deal of calculations,the influence surface of inner force of the control section can be got.By discussing the differences of the stress characteristics of the assembled skew hollow slab bridge and the integral one,this paper provides references for the further calculation of the assembled prestressed concrete skew hollow slab bridge. |
