| 摘 要： | 针对某大跨度预应力混凝土连续箱梁桥在施工阶段出现边跨底板开裂的情况,采用通用有限元分析软件AN-SYS9.0对该桥边跨现浇段锚下局部应力进行了计算分析,分析结果表明,过大的边跨底板纵向预应力是造成开裂的主要原因。

| Abstract: | In view of the bottom slab crack in side spans of a large span P.C.continuous box girder bridge occurred in the construction,the common finite element ANSYS9.0 software is used for analyzing the local stress under the anchorage of this bridge in casted side spans.Results of the analysis showed that too much vertical side spans prestressed in bottom slab is the main reason causing cracking. |
