摘要： 廣珠城際軌道順德站特大橋，橋梁結構布置類型為（39.3+64+39.3）m直線（四線）連續(xù)道岔連續(xù)梁+15孔32m七箱單室梁+（4×32）m（四線）道岔連續(xù)梁+（32+48+32）m緩和曲線連續(xù)梁，七箱單室梁中間三榀濕接后整體架設為全國首例，其箱梁在梁場內(nèi)濕接，架橋機整體提運架工藝，及箱梁滑移梁技術為全國首創(chuàng)。根據(jù)七箱梁現(xiàn)場濕接的經(jīng)驗及其架梁的實際工藝，結合廣珠城際軌道綜合工程ZH-1標順德梁場LC31.5-740運價一體式架橋機架梁工藝，介紹七箱單室梁架設施工工藝。
　　Abstract: The bridge structure of Shunde extra-large bridge on Guangzhou-Zhuhai intercity railway are as follows: four lines straight line continuous girder（39.3+64+39.3）m, 15 seven boxes single-room girders( each one 32 ) m, four lines turnout continuous girder（4×32）m and（32+48+32）m transition curve continuous girder. The technology that the middle three of seven boxes single-room girders which are wet grafted is the first case. Girders wet grafting at beam fabrication and transmitted wholly by bridge erecting machine, and slippage of box beams are all among top technologies in china. According to the experience of seven boxes girder wet grafting and the technology of bridge erection, combined with the technology of bridge erection girder carrying-erecting combined type on Guangzhou-Zhuhai intercity railway large comprehensive project ZH-1V beam field in Shunde LC31.5-740, seven boxes single-room erection construction technology is introduced.

　　0引言
　　隨著中國鐵路跨越式發(fā)展，高速鐵路、客運專線建設已經(jīng)掀起了一個前所未有的施工高潮。城市間的高速公路或鐵路，為避免和其他線路平面交叉、節(jié)省用地、減少路基沉陷（某些地區(qū)），也可不用路堤，而采用高架橋。這種橋因受既有建筑物限制和線路要求，很多彎橋和坡橋。高架線路橋的上部結構，一般多采用簡支梁或連續(xù)梁（或剛架），懸臂梁較為少見。用簡支梁時，為保證橋面行車平順，常做成橋面連續(xù)的簡支梁。這種高架橋幾乎都是把箱梁在梁場預制好后，通過架橋機把箱梁架設到橋墩上。但目前通過架橋機架設的橋梁多數(shù)為單箱單室梁、單箱雙室梁、雙箱單室梁、還有T型梁，廣珠城際軌道順德站特大橋，四線七箱單室梁較為特殊，我項目部針對廣珠城際軌道交通工程ZH-2標段四線七箱梁架設的特殊情況,研究了四線多榀單室箱梁的架設流程、施工工藝。得到了切實可行的七箱單室梁梁架設施工工藝。
