| 標(biāo)題 |
| 軌道板厚度對板式軌道應(yīng)力的影響分析(50 卷) |
| 英文標(biāo)題 |
| Analysis about influence of track slab thickness on stress in slab-type track |
| 摘要 |
| 不同軌道板厚度對板式軌道的受力會產(chǎn)生不同的影響，以單元板式無砟軌道為例,采用有限元方法，進行無砟軌道荷載應(yīng)力分析。分析結(jié)果表明，軌道板厚度的改變對軌道板縱向彎矩的影響最為明顯，增加厚度能降低軌道板配筋量，但在100 MPa CA砂漿情況下其厚度不宜超過0.3 m。 |
