| 減振型板式無砟軌道軌道板受力分析研究(49 卷) |
| 英文標(biāo)題 |
| Analytical study on internal forces in vibration-reduction-type ballastless track slab |
| 摘要 |
| 介紹減振板式無砟軌道的結(jié)構(gòu)組成和計算參數(shù)，建立了梁體有限元計算模型，計算分析了列車荷載作用下減振板式無砟軌道的受力,考慮軌道板受溫度梯度荷載、橋梁撓曲變形，在制造、運輸和施工時對減振軌道板的受力影響，對軌道板在這些因素下的受力進(jìn)行了分析，為結(jié)構(gòu)設(shè)計提供計算 |
