高速公路连续箱梁施工过程中顶板裂缝病害分析及处理

Analysis and Treatment of Roof Crack Deterioration in Highway Continuous Box Girder Construction

结合施工期间主跨(63+114+114+63)m存在顶板局部裂缝病害的公路连续刚构箱梁桥,提出模拟计算与病害特征经验分析相结合的思路和方法,并在此基础上提出了加固措施和预防建议。

In light of the fact that the continuous rigid box girder highway bridges often have the defects of top slab cracks during construction （63 ＋ 114 ＋ 114 ＋ 63 ）m, the author puts forward in this article the ideology and methods of combining analog computation with crack characteristic analysis, and further measures to strengthen or prevent such cracks.
