| Study on treatment of surface cave-in above shallow-buried tunnel with large cross section in soft-weak geological condition |
| 摘要 |
| 以新建貴廣鐵路軟弱地質(zhì)淺埋大斷面東科嶺隧道施工為背景，對(duì)地表塌陷、洞內(nèi)塌方、突泥涌水以及大變形等嚴(yán)重影響施工安全與進(jìn)度的重大問題進(jìn)行研究，得出了地表排水改移、地表塌陷強(qiáng)支護(hù)技術(shù)及工藝方法。提出的地表塌陷區(qū)施作旋噴樁止水墻加井點(diǎn)降水聯(lián)合防排水等工程措施，可 |
