| 基于有限元分析的實(shí)腹式石拱橋合理計(jì)算模式研究(50 卷) |
| 英文標(biāo)題 |
| Study on rational calculating model of solid spandrel stone arch bridge based on finite element analysis |
| 摘要 |
| 針對(duì)中小跨徑實(shí)腹式老舊石拱橋承載能力評(píng)定的問題，可采用平面有限元數(shù)值分析方法，此方法宜建立較為符合實(shí)際的計(jì)算模型。根據(jù)實(shí)際施工過程，將一期恒載與活載、二期恒載等作用分別建模計(jì)算，且考慮填土對(duì)車輛荷載的擴(kuò)散作用，將車輛荷載集中力換算成均布荷載施加于結(jié)構(gòu)中， |
