摘要
以黑龙江省哈尔滨市某公铁两用桥梁为背景,介绍了大跨度单悬臂预应力盖梁的设计要点,以及施工方案对施工阶段盖梁各截面混凝土应力的影响,以期找到施工阶段受力较为合理的架梁顺序,用以指导施工。
Taking certain highway- railway dual function bridge in Harbin City,Heilongjiang Province as background,design features of long- span single cantilever pestressed cap beam and the influence of construction scheme on concrete stress of each section of cap beam in construction stage has been introduced to hope to find the reasonable beam order under stress to give reference to construction.
