文章针对某公路大桥钢-混组合梁结构，设计并制作了2组PBL剪力键结构试件，对其破坏形式、极限承载力与滑移量进行了推出试验研究，分别得到了3孔有贯通钢筋 PBL 键结构试件和3孔无贯通钢筋PBL键结构试件的极限承载力和载荷-滑移曲线。结果对比表明，有贯通钢筋PBL剪力键结构试件的极限承载力高于无贯通钢筋PBL剪力键结构试件约16.6％；采用非线性有限元法对2种试件分别进行了模拟仿真计算，计算结果与试验结果相对误差均小于7％。

According to a practical steel-concrete highway bridge structure ,two types of PBL shear connector structure test samples were designed .The destruction form ,ultimate bearing capacity and sliding value were tested by push-out tests .The ultimate bearing capacities and load-sliding curves of three-port PBL shear connector structure with rebar and without rebar were gotten .The results show that the ultimate bearing capacity of PBL shear connector structure with rebar is higher than that of PBL shear connector structure without rebar by about 16.6% .Meanwhile ,the nonlinear finite ele-ment models were built and the simulation calculations were carried out .The relative error of test val-ues with calculated values is less than 7% .
