| 摘要 |
| 本文以新建廣珠鐵路西江特大橋主橋?yàn)橐劳校接懥舜罂缍冗B續(xù)剛構(gòu)柔性拱橋主梁施工監(jiān)控的方法，結(jié)合結(jié)構(gòu)有限元仿真分析，在施工過程中對(duì)結(jié)構(gòu)線形、掛籃變形、截面應(yīng)力進(jìn)行監(jiān)測(cè)，通過實(shí)測(cè)數(shù)據(jù)進(jìn)行參數(shù)識(shí)別與誤差分析，指導(dǎo)現(xiàn)場(chǎng)施工。實(shí)踐表明，大橋主梁合龍后線形在設(shè)計(jì)運(yùn)行誤差范圍內(nèi)，結(jié)構(gòu)受力正常，施工監(jiān)控效果良好。 |
