| 青藏鐵路多年凍土區(qū)橋梁鉆孔灌注樁施工技術(shù)(36 卷) |
| 英文標(biāo)題 |
| The Construction Technology of Bored Pile in Bridge in Permafrost Region Along Qingzang Railway |
| 摘要 |
| 多年凍土區(qū)橋梁鉆孔灌注樁施工的關(guān)鍵是保護(hù)凍土，最大限度減少外界熱量對(duì)樁體周圍凍土擾動(dòng)，因此，施工中鉆孔和樁身混凝土成為重點(diǎn)研究的技術(shù)。結(jié)合多年凍土特性和青藏鐵路橋梁樁基的施工實(shí)踐，著重介紹了旋挖鉆機(jī)特點(diǎn)和樁身混凝土的施工技術(shù)和體會(huì)。 |
