[提要] 某水庫老閘交通橋是連接水庫大壩與前方基地的惟一交通要道，原框架構(gòu)件載重按照汽－13設(shè)計(jì)，現(xiàn)要求將原框架構(gòu)件按照汽－15進(jìn)行加固改造設(shè)計(jì)。在不影響正常交通的條件下，工程運(yùn)用系統(tǒng)優(yōu)化原理，選擇了預(yù)應(yīng)力人字形斜支柱加固的方法，并進(jìn)行了設(shè)計(jì)及計(jì)算。[關(guān)鍵詞] 框架加固 預(yù)應(yīng)力 斜支柱 系統(tǒng)優(yōu)化A certain traffic bridge by an old reservoir is the unique way connecting dam with frontal base. The frame structure is strengthened as design loads changing from heavy vehicle 13 to heavy vehicle 1 5.Based on systematic optimization, design and application of prestressed herringbone diagonal stanchion strengthening are explored under normal traffic circumstances.The process of manufacturing and installing the bracing set is intrudced also.Keywords: frame strengthening; prestress; diagonal stanchion; systematic optimization參 考 文 獻(xiàn)
