【摘要】：人行懸索橋造型美觀，構(gòu)造簡(jiǎn)單，受力明確，橋梁施工過程不受地形、航道等條件的影響，并且經(jīng)濟(jì)性合理。懸索橋的設(shè)計(jì)理論較成熟，計(jì)算軟件較多，對(duì)各種非線性分析和動(dòng)力分析有足夠的精度。與此同時(shí)，國(guó)內(nèi)雖然修建了很多懸索橋，但對(duì)懸索橋的施工及監(jiān)控卻沒有專門的規(guī)范和手冊(cè)，尤其是對(duì)人行懸索橋，缺乏施工過程控制經(jīng)驗(yàn)及規(guī)范參照，造成一些人行懸索橋達(dá)不到設(shè)計(jì)預(yù)定目標(biāo)，甚至出現(xiàn)安全事故。 本文以某人行懸索橋?yàn)橐劳�，在充分理解設(shè)計(jì)意圖的前提下，分析其施工過程中的難點(diǎn)與重點(diǎn)，在此過程中查閱大量國(guó)內(nèi)外文獻(xiàn)，并通過相關(guān)軟件進(jìn)行有限元計(jì)算分析，得出預(yù)期合理的施工監(jiān)控?cái)?shù)據(jù)。文中闡述的此次施工監(jiān)控包含的主要內(nèi)容有：人行懸索橋主塔施工及監(jiān)控、主梁施工及監(jiān)控、索夾與吊索施工及監(jiān)控、主纜及主梁線形監(jiān)控，并系統(tǒng)地對(duì)主纜線形監(jiān)測(cè)結(jié)果、橋面線監(jiān)測(cè)結(jié)果以及吊索索力測(cè)試結(jié)果進(jìn)行分析。通過理論計(jì)算與現(xiàn)場(chǎng)監(jiān)控結(jié)果的對(duì)比，分析施工誤差并反饋于實(shí)際施工中，對(duì)橋梁的施工過程進(jìn)行了全方位的過程控制，保證了施工安全，并且實(shí)現(xiàn)了該人行懸索橋各項(xiàng)設(shè)計(jì)指標(biāo)達(dá)到設(shè)計(jì)預(yù)期目標(biāo)。本文對(duì)該人行懸索橋的施工以及監(jiān)控過程的重點(diǎn)、難點(diǎn)的分析研究成果，可為類似人行懸索橋的施工及監(jiān)控提供借鑒與參考。
[Abstract]:The construction process of the bridge is not affected by topography and waterway, and the economy is reasonable. The design theory of suspension bridge is mature and there are many calculation softwares. It has enough precision for nonlinear analysis and dynamic analysis. At the same time, although many suspension bridges have been built in China, there are no special specifications and manuals for the construction and monitoring of suspension bridges, especially for pedestrian suspension bridges, and lack of experience in construction process control and reference to specifications. As a result, some pedestrian suspension bridges fail to reach the design target, and even safety accidents occur. Based on a certain suspension bridge, under the premise of fully understanding the design intention, this paper analyzes the difficulties and key points in the construction process, and in the process, looks up a large number of domestic and foreign literature, and carries on the finite element calculation and analysis through the related software. Get the expected reasonable construction monitoring data. The main contents of this construction monitoring include: construction and monitoring of main tower of pedestrian suspension bridge, construction and monitoring of main beam, construction and monitoring of cable clip and slings, monitoring of main cable and main beam alignment, and systematic monitoring results of main cable shape. The monitoring results of bridge deck line and the test results of cable suspension force are analyzed. Through the comparison between the theoretical calculation and the field monitoring results, the construction error is analyzed and fed back to the actual construction, and the construction process of the bridge is controlled in an all-round way, which ensures the construction safety. The design target of the suspension bridge has been achieved. In this paper, the emphases and difficulties of the construction and monitoring process of the suspension bridge can be used as reference for the construction and monitoring of the similar suspension bridge.
