簡介：DESIGNANDCONSTRUCTIONTECHNOLOGYRESEARCHOFGUYEDTRAVELERSOFCONCRETECABLESTAYEDBRIDGEWITHSINGLECABLEBVHONGGUANGWANG，一INSTRUCTORNAMESUJUANGEMASTEROFENGINEERING一一SCHOOLOFCIVILENGINEERINGMAY2014摘要斜拉橋是一種組合式橋梁，它具有梁體受壓、斜拉支撐受拉的特點(diǎn)。它發(fā)揮了拉索抗拉能力強(qiáng)，混凝土梁或鋼箱梁抗壓能力大的特點(diǎn)，因其跨度大，整體剛度大，在大跨徑橋梁中得到了較好的應(yīng)用。斜拉橋便于采用懸臂法施工，但由于拉索與主梁和索塔連接構(gòu)造復(fù)雜，且三者之間的內(nèi)力和變形相互關(guān)聯(lián)性十分密切，因而施工難度高。為了保證橋梁施工過程及最終成橋線形和內(nèi)力符合設(shè)計(jì)要求，須在施工前撰寫完善的施工步驟和監(jiān)控方案。本文以肇慶市閱江大橋?yàn)檠芯繉ο?，對單索面斜拉橋施工中的關(guān)鍵技術(shù)進(jìn)行了分析研究，完成了以下工作并得出重要結(jié)論。1根據(jù)閱江大橋的特點(diǎn)，采用掛籃施工分段澆筑主梁混凝土方法。利用有限元軟件ANSYS對主梁中央單索面掛籃在四種施工工況下進(jìn)行了受力分析和變形計(jì)算，得出各工況下主要構(gòu)件的應(yīng)力及變形結(jié)果，根據(jù)計(jì)算結(jié)果設(shè)計(jì)掛籃截面，并選擇合適的鋼材。2根據(jù)閱江大橋的結(jié)構(gòu)特點(diǎn)及現(xiàn)場情況，掛籃安裝采用整體提升方法，并制定了詳細(xì)的操作步驟。掛籃安裝后進(jìn)行了靜載試驗(yàn)，試驗(yàn)以掛籃澆筑最重節(jié)段混凝土荷載的110倍作為最大荷載，采用堆麻袋裝砂的加載方式，輔以腹板位置加堆鋼筋來模擬主梁混凝土澆注全過程，據(jù)此得出掛籃的非彈性變形和彈性變形，前者已經(jīng)消除，后者通過預(yù)抬標(biāo)高來予以調(diào)整。3本文詳細(xì)介紹了主梁及斜拉索的施工工藝及流程，詳細(xì)闡述了牽索掛籃的特點(diǎn)、牽索掛籃施工工藝流程、掛籃行走與定位、模板工程、鋼筋預(yù)應(yīng)力工程、預(yù)埋件施工、混凝土工程、斜拉索施等施工工藝。通過對以上內(nèi)容的研究與分析，得出如下重要結(jié)論1箱梁兩側(cè)斜腹板及翼緣板下方采用桁架式支承結(jié)構(gòu)，既滿足了強(qiáng)度和剛度需要，同時減少了整個掛籃的下部結(jié)構(gòu)重量，使用起來更加輕便；同時兩側(cè)桁架與主梁結(jié)構(gòu)采用銷軸連接，方便了現(xiàn)場拆裝。2前支點(diǎn)牽索結(jié)構(gòu)為雙向可調(diào)節(jié)系統(tǒng)，有更強(qiáng)的通用性。可以適應(yīng)空間三個方向均有一定傾斜度的斜拉索的牽引和張拉。3本掛籃前、后支點(diǎn)及錨桿處均采用40CRMO材質(zhì)的拉桿，避免了采用精軋螺紋鋼容易發(fā)生脆斷破壞的風(fēng)險。關(guān)鍵詞橋梁工程斜拉橋；單索面；牽索掛籃；設(shè)計(jì)；施工Ⅲ
