| Analysis of affected factors of longitudinal force in CRTS Ⅱ slab-type track on continuous girder bridge under temperature effect |
| 摘要 |
| 本文以一段大跨連續(xù)梁橋?yàn)檠芯繉?duì)象，建立橋上CRTSⅡ型板空間一體化模型，采用有限元方法，計(jì)算橋上CRTSⅡ型板式無砟軌道在溫度作用下各部件的縱向力，并分析不同因素對(duì)各部件縱向力的影響。通過計(jì)算分析表明：對(duì)于本文中的連續(xù)梁橋，隨著聯(lián)合板伸縮剛度的增大，聯(lián)合板、固結(jié) |
