| 標(biāo)題 |
| 客運(yùn)專線無(wú)砟軌道無(wú)縫線路鎖定軌溫確定方法的探討(29 卷) |
| 英文標(biāo)題 |
| Study on the Determination Method for Stress Free Temperature ofCWR in Ballastless Track of Passenger Dedicated Line |
| 摘要 |
| 根據(jù)客運(yùn)專線無(wú)砟軌道無(wú)縫線路的結(jié)構(gòu)和受力特點(diǎn)，采用現(xiàn)場(chǎng)試驗(yàn)、調(diào)研和動(dòng)力仿真等方法對(duì)既有無(wú)砟軌道無(wú)縫線路鎖定軌溫的影響因素進(jìn)行系統(tǒng)分析。研究結(jié)果表明：鎖定軌溫降低后，無(wú)縫線路溫升幅度增大，溫降幅度減小，將導(dǎo)致無(wú)縫線路施工和維護(hù)困難、鋼軌發(fā)生碎彎幾率增大等問(wèn) |
