| Discussion on value of reaction coefficient for ballastless track bed above subgrade |
| 摘要 |
| 在使用溫克勒地基模型對土質(zhì)路基無砟軌道進(jìn)行內(nèi)力分析與結(jié)構(gòu)設(shè)計時，基床反力系數(shù)K是最為重要的參數(shù)，其取值正確與否直接影響到計算結(jié)果的準(zhǔn)確性?；卜戳ο禂?shù)K的數(shù)值不僅與土體性質(zhì)有關(guān)，而且與加載速度、荷載面積大小、荷載形狀及沉降量大小等因素有關(guān)。在介紹土質(zhì)路基無 |
