基于线弹性理论，探讨了简支梁桥连接板混凝土开裂问题，并对桥梁连接板进行了理论分析。同时，推导了桥面板应力计算公式，定量分析了桥面板连续破坏的原因。在分析其破坏机理的基础上，提出了一种新型的钢-混凝土组合扁连接板。足尺模型试验和有限元分析结果表明，该结构能够改变连接板内部内力的传递路径，从而有效地防止混凝土开裂。研究发现，影响连板破坏的主要因素是梁端上翘、纵向拉力作用和梁端转动。此外，梁板间的无粘结区可以有效地降低连续应力，从而减轻桥面板的损伤。本文的研究成果可为新型桥梁连接板和无伸缩缝桥梁的进一步研究和开发提供参考和指导。
Based on linear elastic theory, the concrete cracking problem of link slab on simply supported beam bridge was explored and theoretical analysis of bridge link slabs were carried out. Meanwhile, the formulas for calculating the stress of link slab were deduced and the cause for continuous damage of bridge deck was quantitatively analyzed. On the base of analysis of its failure mechanism, a new type of steel-concrete composite flat link slab was proposed. The results of full-scale model tests and finite element (FE) analysis indicated that it can alter the transfer path of internal forced inside the link slab and then concrete cracking can be prevented effectively. It was found that the main factors to link slab failure were influentially descending from girder end upturning, longitudinal tensile action and girder end rotation. Furthermore, the unbonded region between girder and link slab can effectively decrease the continuous stress and then alleviate the damage to bridge deck. All those results in this paper can be used as a reference and guidance for further research and development of new type of bridge link slab and jointless bridge.
