| 大跨度預(yù)應(yīng)力混凝土連續(xù)箱梁橋收縮徐變效應(yīng)分析(49 卷) |
| 英文標(biāo)題 |
| Analysis of shrinkage-creep effect of large-span prestressed concrete continuous box girder bridge |
| 摘要 |
| 針對(duì)武廣客運(yùn)專線某大跨度預(yù)應(yīng)力混凝土箱梁橋,采用MIDAS/Civil 結(jié)構(gòu)分析軟件,結(jié)合國內(nèi)外幾種規(guī)范中徐變系數(shù)的計(jì)算公式,計(jì)算其在鋪砟后1年內(nèi)梁體的變形,并將其與現(xiàn)場(chǎng)實(shí)測(cè)的數(shù)據(jù)比較。通過現(xiàn)場(chǎng)實(shí)測(cè)變形與理論分析結(jié)果的對(duì)比得出,采用GL2000 模型的計(jì)算值與實(shí)測(cè)值吻合良好,為實(shí) |
