| 鐵路橋梁樁基施工中的喀斯特溶洞處理(52卷) |
| 英文標(biāo)題 |
| Treatment of karst cave in construction of pile foundation of railway bridge |
| 摘要 |
| 結(jié)合南寧至廣州鐵路第八標(biāo)段鼎湖特大橋樁基施工溶洞處理實(shí)際情況,介紹了巖溶地區(qū)地基處理的3種方法,即拋填片石和黏土填充法、溶洞注漿填充法和鋼護(hù)筒跟進(jìn)法,并詳細(xì)說(shuō)明了3種溶洞處理方法的適用條件和操作步驟。通過(guò)3種方法的交替使用,對(duì)巖溶地區(qū)地基處理取得了比較滿意的效果,保證了樁基礎(chǔ)施工質(zhì)量和進(jìn)度,為類似工程提供借鑒。 |
