| Additional Longitudinal Force of CWR Track on Bridge Caused by Temperature Difference between One Side and Another Side of Pier |
| 摘要 |
| 采用單位荷載法計(jì)算橋墩溫差荷載引起的墩頂縱向位移。根據(jù)梁軌相互作用原理，建立“軌—梁—墩”有限元模型，計(jì)算橋墩溫差引起的橋上無(wú)縫線路鋼軌附加力，研究橋墩溫差引起的鋼軌附加力的分布規(guī)律及其影響因素。研究表明：多跨簡(jiǎn)支梁橋墩溫差引起的鋼軌附加力的最大壓力出現(xiàn) |
