1 前 言 現(xiàn)代高速鐵路建設(shè)中，橋梁建設(shè)技術(shù)已經(jīng)成為不可或缺的關(guān)鍵技術(shù)之一。橋梁是高速鐵路土建工程的重要組成部分，主要功能是為高速列車提供平順、穩(wěn)定的橋上線路，以確保運(yùn)營的安全和旅客乘坐的舒適。從我國高速鐵路橋梁建設(shè)的理念入手，分析了我國高速鐵路橋梁建設(shè)的設(shè)計(jì)特點(diǎn)，介紹了高速鐵路橋梁建設(shè)中采用的關(guān)鍵技術(shù)，具有一定參考 價(jià) 值。 山東職業(yè)學(xué)院畢業(yè)論文 2 1 橋梁施工技術(shù)簡介 高速鐵路對(duì)橋梁上部結(jié)構(gòu)豎向和橫向剛 度要求較高，并要求保證結(jié)構(gòu)的整體性，因此在橋梁設(shè)計(jì)中除采用一部分特殊設(shè)計(jì)的橋梁外（如連續(xù)梁，拱橋等），標(biāo)準(zhǔn)梁一般采用箱型梁或橫向采用預(yù)應(yīng)力來并聯(lián)的 T 型梁。 從實(shí)際出發(fā)，高速鐵路常用跨度橋梁的施工將會(huì)采用多種制梁、架設(shè)方法，如現(xiàn)場(chǎng)預(yù)制整孔箱梁、重型架橋機(jī)架設(shè)；現(xiàn)場(chǎng)預(yù)制 T 型梁、用龍門架或一般吊機(jī)架設(shè)后聯(lián)成整體；在移動(dòng)支架上逐孔灌注混凝土梁；在橋位固定腳手架上制梁；橋頭分段制梁，逐孔頂推等。 下面將簡要介紹高速鐵路橋梁上部結(jié)構(gòu)的施工方法，并概括各種方法的施工特點(diǎn)。 就地澆筑法是在
