摘 要:为研究装配式钢-混凝土空心路面板的接缝传荷能力,该文利用ABAQUS建立有限元模型开展数值分析,对比未脱空与脱空状态下的路面板接缝传荷系数及最大弯沉值的变化规律,进一步分析其传荷能力。结果表明:当板块出现脱空时,随脱空面积增大,板块传荷系数有所降低,但达到一定脱空深度时,板块的传荷系数变化不明显;板块未出现脱空时,随荷载增加,板块最大弯沉值变化较为明显,当荷载大于200 kN时,弯沉值变化较小;不同空心形式对路面板的传荷系数也有一定影响;该文装配式钢-混凝土空心路面板接缝传荷系数在任何情况下均大于97%,受荷板与非受荷板的最大弯沉值不高于60(0.01 mm),接缝均可正常工作,且传荷能力较好,可有效防止错台问题。In order to study the joint load transfer capacity of a prefabricated steel-concrete hollow pavement slab,a finite element model was established with ABAQUS to carry out numerical analysis.The variation laws of the maximum deflection value and joint load transfer coefficient of the pavement slab with and without cavitation were compared to analyze the load transfer capacity.The results show that when cavitation occurs in the slab,the load transfer coefficient of the slab decreases with the increase in the cavitation area,but the load transfer coefficient of the slab does not change significantly when the cavitation depth reaches a certain level.When there is no cavitation in the slab,the maximum deflection value of the slab changes obviously with the increase in load,and when the load is greater than 200 kN,the deflection value changes little.Different hollow forms also have a certain influence on the load transfer coefficient of the slab.The joint load transfer coefficient of the prefabricated steel-concrete hollow pavement slab is greater than 97%in any case,and the maximum deflection values of the loaded slab and the non-loaded slab are not higher than 60(0.01 mm),so the joint can work normally,indicating good joint load transfer capacity and effectively preventing the misalignment problem.
