摘　　要：为了测试某单箱双室连续弯箱梁桥在正常使用条件下的实际承载力和结构变形是否满足设计要求,对其进行静载试验研究。结果表明,挠度和应力的实测曲线与理论曲线一致性较好,与之对应的校验系数在要求范围之内,弯箱梁桥的刚度和强度均合乎设计要求,未见明显裂缝。In order to test whether the actual bearing capacity and structural deformation of a curved box girder bridge with a box and double chambers continuously meet the design requirements under normal condition,the static load test is carried out.The results suggest that the measured deflection and stress curves are in good agreement with the theoretical curves,and that the relevant calibration coefficients are in a reasonable range,the stiffness and strength of the curved box girder bridge meet the design requirements,with no obvious cracks.

关 键 词：弯箱梁桥 静载试验 挠度 应力 裂缝
