| 高速鐵路巖溶地質(zhì)條件下鉆孔樁施工工藝試驗(yàn)研究(37 卷) |
| 英文標(biāo)題 |
| Research on the Construction Technology of High-speed Railway Bored Piles Under the Condition of Karst Geology |
| 摘要 |
| 石灰?guī)r巖溶發(fā)育地區(qū)，施工過程中塌孔、卡鉆、埋鉆現(xiàn)象極易發(fā)生，威脅施工安全，影響工程質(zhì)量。成孔方法，特別是溶洞的處理是成樁的關(guān)鍵工序。在溶洞處理過程中根據(jù)溶洞的大小，采用填粘土塊和片石，灌注低標(biāo)號混凝土、壓漿，壓雙液漿，灌砂壓漿，鋼護(hù)筒跟進(jìn)的施工方案，能保 |
