| 桃河特大橋主跨65 m鋼—混結合梁施工過程控制(52卷) |
| 英文標題 |
| Construction control over main span of 65 m steel–concrete composite girder of Taohe super large bridge |
| 摘要 |
| 采用虛擬層合板—殼—梁—實體組合單元法對桃河特大橋施工過程進行了有限元仿真分析,并與實測結果進行了對比,得出如下結論： 虛擬層合板—殼—梁—實體組合單元法能夠以少量的單元精確模擬結合梁的幾何細節(jié),避免了結合梁施工過程力學分析中的重復建模、節(jié)點耦合等難題;“U”型鋼梁在移梁架設過程中各控制截面的實測應力變化較小,架設過程平穩(wěn)、順利;各施工階段鋼梁和鋼筋混凝土橋面板應力實測值與理論值較為吻合。 |
