| 標(biāo)題 |
| 基于兩步分級(jí)法和現(xiàn)場(chǎng)監(jiān)控量測(cè)的隧道圍巖穩(wěn)定性研究(49 卷) |
| 英文標(biāo)題 |
| Study on stability of tunnels surrounding rock based on two-step-method and in-situ monitoring measurement |
| 摘要 |
| 圍巖分級(jí)是隧道穩(wěn)定性評(píng)價(jià)的基礎(chǔ)，采用兩步分級(jí)法從定性和定量?jī)蓚€(gè)角度出發(fā)，綜合多因素指標(biāo)評(píng)判分級(jí)，為調(diào)整優(yōu)化相應(yīng)工程措施提供重要依據(jù)。通過現(xiàn)場(chǎng)監(jiān)控量測(cè)，獲得反映圍巖和支護(hù)結(jié)構(gòu)狀態(tài)的數(shù)據(jù)，對(duì)其進(jìn)行回歸分析，根據(jù)圍巖變形量和變形速率判據(jù)，對(duì)圍巖穩(wěn)定性進(jìn)行評(píng)價(jià)， |
