摘要
针对目前公路中大量拓宽改造的空心板桥,通过计算旧桥及不同拓宽方式下旧桥各板的荷载横向分布系数,探讨其变化对桥梁结构的影响,并进行对比分析,以确定最优拓宽方案,为日后空心板桥拓宽改造提供理论指导。
According to widening the hollow slab bridge in highway at present,the load transverse distribution coefficient of each plate of the old bridge is calculated in the different way of widening the old bridge,and the effects caused by the changes to the potential bearing capacity of bridge structure are studied.Compare the different transverse load coefficients to determine the optimal scheme and provide theoretical guidance for widening hollow slab bridge in future.
