| 客運(yùn)專線鐵路簡(jiǎn)支梁橋墩臺(tái)縱向線剛度分析研究(50 卷) |
| 英文標(biāo)題 |
| Analysis study on longitudinal linear rigidity of pier and abutment for simply-supported girder bridge on passenger-dedicated railway |
| 摘要 |
| 從梁軌共同作用機(jī)理出發(fā)，建立了客運(yùn)專線簡(jiǎn)支梁橋梁軌共同作用計(jì)算模型，針對(duì)有砟軌道與無(wú)砟軌道各自的特點(diǎn)，通過(guò)無(wú)縫線路橋梁縱向力分析計(jì)算，系統(tǒng)研究了橋梁墩臺(tái)縱向線剛度對(duì)橋梁和軌道結(jié)構(gòu)的影響，提出了不設(shè)置鋼軌伸縮調(diào)節(jié)器的常用跨度簡(jiǎn)支梁橋墩臺(tái)縱向線剛度合理取值， |
