| 蘭新鐵路路基土凍脹特性試驗(yàn)研究(50 卷) |
| 英文標(biāo)題 |
| Experimental study on frost heave performance of subgrade soil on Lanzhou-Xinjiang railway |
| 摘要 |
| 本文通過用不同含水量、不同密實(shí)度的封閉系統(tǒng)凍脹試驗(yàn)和開放系統(tǒng)凍脹試驗(yàn)，研究了蘭新線路基土凍脹特性。試驗(yàn)結(jié)果表明，在封閉系統(tǒng)和開放系統(tǒng)下凍脹率均隨含水量的增大而增長(zhǎng)，隨壓實(shí)度增加而減少。由于水分的補(bǔ)給，開放系統(tǒng)下的凍脹率遠(yuǎn)大于封閉系統(tǒng)下的凍脹率。 |
