| 英文標(biāo)題 |
| Study on construction technology of consolidation grouting under super-high penetration pressure without overburden weight |
| 摘要 |
| 以最大壓力水頭1 100 m的錦屏二級(jí)水電站引水隧洞工程為背景，對無蓋重固結(jié)灌漿施工技術(shù)進(jìn)行研究。運(yùn)用灌漿理論及技術(shù)，結(jié)合錦屏工程地質(zhì)及圍巖條件，確定了固結(jié)灌漿鉆孔孔徑、檢查孔孔徑、彈性波檢測孔孔徑均為56 mm,先導(dǎo)孔孔徑76 mm、抬動(dòng)觀測孔孔徑91 mm、漿液擴(kuò)散半徑檢測 |
