| 節(jié)理傾角對層狀巖體大斷面隧道穩(wěn)定性研究(51 卷) |
| 英文標(biāo)題 |
| Study on influence of joint plane angle on stability of large-profile tunnel in layered rock mass |
| 摘要 |
| 以山西大梁山隧道工程為研究對象，研究不同節(jié)理傾角隧道圍巖穩(wěn)定性以及錨桿力學(xué)響應(yīng)，闡明其不同于傳統(tǒng)松散介質(zhì)理論的層狀巖質(zhì)隧道失穩(wěn)模式。主要得出如下結(jié)論：①節(jié)理面是隧道失穩(wěn)破壞關(guān)鍵所在；②傾角較小時，拱頂容易發(fā)生彎折破壞；③錨桿串連數(shù)層層狀巖體，增大層間摩阻 |
