双柱式桥墩盖梁设计中几个问题的探讨

Study on Design of the Beam Supported on Double-columnar Bridge Pier

运用力学的基本理论,对双柱式桥墩简支双悬臂盖梁的内力分布进行了分析,推导出合理的悬臂长度及其分跨比,并分析了支承宽度对内力和位移的影响。

Based on mechanical fundamental theory,the internal force distribution of double-column support cantilever cover beam is analyzed,and the reasonable proportion of spans is deduced.The influence of supporting width on internal force and deflection is analyzed.
