| 廈門燒湯溪大橋自振特性及考慮列車作用的穩(wěn)定性分析(50 卷) |
| 英文標(biāo)題 |
| Dynamic property of Xiamen Shaotangxi bridge and its stability analysis considering train operating |
| 摘要 |
| 以跨度為96 m的廈門燒湯溪大橋?yàn)槔?，采用大型有限元軟件MIDAS/Civil建立下承式鋼管混凝土拱橋的空間計(jì)算模型，分析了橋梁的自振特性，在此基礎(chǔ)上對有列車活載參與作用下的橋梁穩(wěn)定性做了初步探討，得出列車活載對橋梁穩(wěn)定性的影響范圍，結(jié)果可為同類拱橋的設(shè)計(jì)及動力特性分析 |
