| 宜萬鐵路大支坪隧道高壓富水溶腔處理技術(shù)(51 卷) |
| 英文標(biāo)題 |
| Treatment technology of high pressure water-rich karst cavern in Dazhiping tunnel on Yichang-Wanzhou railway |
| 摘要 |
| 根據(jù)地表降雨量與洞內(nèi)涌水時間、涌水量、水壓的關(guān)系，采用作業(yè)面鉆孔泄水、臨界控制爆破揭示溶腔體、高位支洞排水等釋能降壓措施，提供溶腔處理的安全作業(yè)環(huán)境。在宜萬鐵路大支坪隧道的高壓富水、充填性巖溶區(qū)段施工中，綜合采用帷幕注漿預(yù)加固地層、釋能降壓技術(shù)，較好地解 |
