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)構(gòu)特點(diǎn)，提出了地震行波效應(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(jī)懸臂拼裝施工技術(shù)，根據(jù)施工仿真計(jì)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(shí)簡(jiǎn)單介紹桁式組合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:若忽略梁段局部變形,則預(yù)拼線形的誤差會(huì)隨著懸臂拼裝的進(jìn)行不斷放大,梁段頂、底板處的焊縫質(zhì)量和焊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.
當(dāng)斜拉索索力在施工張拉中存在誤差時(shí)，主梁和主塔會(huì)產(chǎn)生附加彎矩，當(dāng)懸臂施工過程中懸臂長(zhǎng)度增大時(shí)斜拉橋主梁就會(huì)發(fā)生出平面的變形，如果不及時(shí)調(diào)整將造成合龍困難甚至引起全橋的破壞。
