摘　　要：通过对PK板的预应力损失理论分析,抗弯性能试验研究及ABAQUS有限元模拟,得出试验结果及分析结论:PK板的抗弯试验与有限元模拟结果表明,PK板破坏属延性破坏,其抗弯性能、开裂荷载和极限承载力均满足设计要求;得出了模拟PK板抗弯性能的有效的ABAQUS模型及模拟参数,与试验结果吻合较好,为PK板在施工阶段的应用提供了试验数据和理论依据。Based on the theoretical analysis of the prestressing loss of PK slab,experimental study on the flexural performance of PK slab and finite element simulation in ABAQUS,the result of experimental and analysis was: Based on the bending experiment and finite element simulation of PK specimens,Further verified the destruction of PK slab belongs to ductile failure,the flexural behavior,cracking load and ultimate strength fully meet the design requirement;Obtained the effective ABAQUS model of PK slab's flexural performance,simulation parameters,and had good agreement with the test results,this paper provided the experimental data and theoretical basis for the PK slab's construction stage.
