| Key technologies of CRTS-II-type track slab prefabricated at production line (productivity: 2×42 blocks) |
| 摘要 |
| 根據(jù)混凝土平板預(yù)制構(gòu)件長線臺座法生產(chǎn)經(jīng)驗，生產(chǎn)線最佳長度為120 m，結(jié)合CRTS Ⅱ型軌道板特點提出了42塊CRTS Ⅱ型軌道板生產(chǎn)線設(shè)計方案，建立有限元模型進行了受力計算，開展了張拉臺座設(shè)計；對42塊軌道板生產(chǎn)線張拉和放張時模板位移、回彈、預(yù)應(yīng)力和摩阻力損失、張拉梁中 |
