【摘要】 某水库老闸交通桥是连接水库大坝与前方基地的惟一交通要道 ,原框架构件载重按照汽 - 13设计 ,现要求将原框架构件按照汽 - 15进行加固改造设计。在不影响正常交通的条件下 ,工程运用系统优化原理 ,选择了预应力人字形斜支柱加固的方法 ,并进行了设计及计算更多还原

【Abstract】 A certain traffic bridge by an old reservoir is the unique way connecting dam wi th frontal base.The frame structure is strengthened as design loads changing fr om heavy vehicle 13 to heavy vehicle 15.Based on systematic optimization,design and application of prestressed herringbone diagonal stanchion strengthening are explored under normal traffic circumstances.The process of manufacturing and ins talling the bracing set is intrudced also.更多还原
