| Stability study on surrounding rock of Jinping Ⅱ-grade hydro-power super-large cross-section tunnel |
| 摘要 |
| 以超埋深、高地應(yīng)力條件下的錦屏二級(jí)水電站隧洞施工為背景，對(duì)特大斷面隧洞開(kāi)挖圍巖穩(wěn)定性進(jìn)行研究。依據(jù)圍巖地質(zhì)和斷面形狀與尺寸，結(jié)合隧道工程理論與方法，確定了監(jiān)測(cè)斷面并在各斷面安裝埋設(shè)了錨桿應(yīng)力計(jì)、多點(diǎn)變位計(jì)和反射膜片，通過(guò)對(duì)TBM組裝洞現(xiàn)場(chǎng)監(jiān)測(cè)并對(duì)實(shí)測(cè)數(shù)據(jù)進(jìn)行 |
