桥面铺装对简支空心板桥受力行为的影响研究

为了研究桥面铺装层对简支空心板桥受力性能的影响,将有限元计算结果与实桥静载试验结果进行了对比,分析了考虑及不考虑铺装层两种情况下的空心板桥在受力行为上的差异,研究了设有不同设计参数或状态铺装层的空心板桥受力特性的差异及其变化规律;研究结果表明铺装层可以有效地削减简支空心板桥的反应;通过加厚铺装层、增强连续性可以改善空心板桥的受力,其中采用桥面连续结构方法效果更为明显.研究结果对同类桥梁设计有一定的借鉴意义.

Research on force behavior influenced by deck pavement to the simply supported hollow slab

In order to study the force behavior influenced by the deck pavement to the simply supported hollow slab,the finite element calculation results are compared with the static load test results.The differences while mechanical behavior of hollow slab deck pavement is consided or not are analyzed,the different mechanical properties and variation of deck pavement with different structure design parameters or state to the hollow slab are also studied.Study results indicate that pavement can cut hollow slab bridge response effectively.Consideration may be given through the thicker pavement and enhanced continuity to improve the slab,which employs a continuous deck structure in a more obvious way.The research provides some reference for the design of similar bridges.
