| 摘 要： | 结合上河桥第八孔2#箱梁的施工实践,对该片箱梁箱内混凝土表面存在的局部缺陷进行了分析。为分析局部缺陷对该梁承载能力的影响大小,对箱梁进行了静载试验,试验采用砂袋加载的方式,结果表明该施工缺陷对箱梁的承载能力影响较小,能够满足设计要求。为了不影响结构的耐久性,对该箱梁缺陷的修补提出了建议。

| Abstract: | Because of the construction defect of 8-2~#box girder of Shanghe bridge,the static loading test was done to identify the bearing capacity of the box girder.Through the contrast of the theoretical value and the actual value from the test,the bearing capacity of the box girder is hardly affected by its construction defect and the bearing capacity of the box girder meets the demand of the design.The suggestion for repairing the construction defect is also provided here. |
