| 標(biāo)題 |
| 寬疊合梁斜拉橋屈曲穩(wěn)定分析(51 卷) |
| 英文標(biāo)題 |
| Analysis of buckling stability of cable-stayed bridge with wide composite girder |
| 摘要 |
| 針對(duì)寧波甬江特大橋的聯(lián)塔四索面斜拉橋工程，詳細(xì)分析了各施工階段的失穩(wěn)模態(tài)，結(jié)果表明該橋各施工階段穩(wěn)定安全系數(shù)滿足規(guī)范值，有較高的穩(wěn)定安全系數(shù)。分析結(jié)果為設(shè)計(jì)提供了理論依據(jù)，并為聯(lián)塔斜拉橋的穩(wěn)定分析提供參考。 |
