摘要
某连续梁桥在桥梁交验荷载试验过程中发现箱梁跨中合龙段出现箱梁底板垂直跨径方向裂缝病害,通过施工中预埋传感器监测数据,分析裂缝产生的可能原因,并采用组合加固方案对箱梁底板进行加固。
continuous beam; cross combinations and strengthening of crack closure segmentsAbstract： The vertical direction of cracks was found on the bottom of the box girder closure segments in a con- tinuous girder bridge load test process. Then the reason of cracks was analysised through the con struction of embedded sensor monitoring and thereinforcement scheme was put forword.
