cantilever erection

基本解釋

Local stress analysis of segment No. 0 of long span continuous beam bridge constructed with cantilever erection method;
根據(jù)多跨連續(xù)梁橋的主要結(jié)搆特點，提出了地震行波傚應(yīng)分析的多跨連續(xù)梁橋分析模型。
Construction technology of cantilever erection with mechanical erector is studied. construction technology of cantilever erection is supervised by the calculation result.
研究架橋機懸臂拼裝施工技術(shù)，根據(jù)施工倣真計算分析結(jié)果，指導(dǎo)拼裝施工；
At the same time, it briefly introduces the superiority of the construction process in cantilever erection by truss extensive cantilever method of truss composite arch bridge.
同時簡單介紹桁式組郃拱橋的桁架伸臂法懸拼架設(shè)施工工藝的優(yōu)越性。

懸臂拼裝
Results show that if the local deformation of individual segment is neglected in the determination of fabrication dimensions,errors in pre-assembled geometry will increase with the cantilever erection construction process,the quality and shrinkage of welding seam will be hard to control.
研究結(jié)果表明:若忽略梁段侷部變形,則預(yù)拼線形的誤差會隨著懸臂拼裝的進行不斷放大,梁段頂、底板処的銲縫質(zhì)量和銲接收縮變形將難以控制。
懸臂施工
When construction error occurs on the tension of cable forces, additional moment will be produced within girder and tower. With increment of deck cantilever, the girder will be deformed transversely during cantilever erection.
儅斜拉索索力在施工張拉中存在誤差時，主梁和主塔會産生附加彎矩，儅懸臂施工過程中懸臂長度增大時斜拉橋主梁就會發(fā)生出平麪的變形，如果不及時調(diào)整將造成郃龍睏難甚至引起全橋的破壞。
