摘要:为研究剪力连接度对部分充填式窄幅钢箱-混凝土组合连续梁相对滑移的影响，设计3片不同抗剪连接度试验组合梁进行单调加载试验，并利用有限元模型对部分充填式钢箱-混凝土组合连续梁相对滑移进行抗剪连接度参数分析。结果表明：部分充填式钢箱-混凝土组合连续梁的相对滑移随着抗剪连接度的增大而减小；保证组合梁刚度和承载能力的条件下，在 0.4~1内调节抗剪连接度，可使栓钉连接效果最佳；抗剪连接度对部分充填式钢箱-混凝土组合连续梁的变形和承载能力有一定影响，特别是负弯矩区抗剪连接度影响最大。

Abstract:In order to study the influence of shear connection degree on the relative slip of the partially-filled narrow-width steel box-concrete composite continuous beam， three sets of different shear connector test composite beams were designed for monotonic loading experiments. By using the finite element model，the relative slip of steel box-concrete composite continuous beam with partial filling was analyzed，and the process and distribution characteristics of the interface slip development of steel box-concrete composite continuous beam with partial filling were obtained. The results showed that the relative slip of partially filled steel box-concrete composite continuous beam decreased with the increase of shear joint degree. When the stiffness and bearing capacity of composite beam were guaranteed，the shear connection degree could be appropriately adjusted within the range of 0.4 ~1 to make the best effect of bolt ；The degree of shear connection had certain affect for deformation and bearing capacity of partially filled narrow-width steel box-concrete composite continuous beams，especially the degree of shear connection in the negative moment zone had a greater influence on the relative slip of the composite beam interface.
