摘　　要：模拟实际工程,采用有机玻璃按1∶30的几何尺寸,制作3跨曲线连续宽箱梁模型。通过静载试验,实测得到了曲线宽箱梁的应力与挠度横向分布规律,分析了曲线宽箱梁内、外侧受力的不均匀性,包括支座反力、应力及挠度的不均匀性。有限元分析结果与试验数据比较,表明两者吻合较好。This paper simulates the practical engineering,using plexiglass to make a three-span continuous wide curved box girder model by the geometry scale ratio 1 ∶30.Through the static load test, we got the distribution about the stress and deflection of the wide curved continuous box girder,analyzed the uneven force of the curved bridge inside and outside,including the reaction force,stress and deflection inhomogeneity.Compared the finite element analysis results and experimental data,the results show both are in good agreement.
