| 哈大鐵路客運(yùn)專線路基填料凍脹性試驗(yàn)研究(51 卷) |
| 英文標(biāo)題 |
| Experimental study on frost heave of subgrade filling material of Harbin-Dalian passenger-dedicated railway |
| 摘要 |
| 路基變形控制是嚴(yán)寒地區(qū)客運(yùn)專線的難點(diǎn)，消除凍脹危害是路基設(shè)計(jì)、施工重點(diǎn)考慮的問題，填料是影響路基凍脹的最主要因素。通過對典型A、B組填料凍脹性的試驗(yàn)研究，分析了填料凍脹性與含水率、細(xì)粒摻量、摻配土質(zhì)、水分變化、干密度之間的關(guān)系，對路基填料選擇和現(xiàn)場施工提出 |
