| 英文標(biāo)題 |
| Mechanical response study on construction of large-cross-section tunnel with small distance apart |
| 摘要 |
| 通過對軟弱圍巖條件下的大斷面小凈距隧道采用不同施工方案及步驟時(shí)的力學(xué)響應(yīng)研究，針對雙側(cè)壁導(dǎo)坑法、CD法、上下臺階法等幾種施工方法對圍巖變形、地表沉降、圍巖應(yīng)力、圍巖穩(wěn)定性等進(jìn)行對比分析，確定了適合軟弱圍巖條件下大斷面小凈距公路隧道的合理施工方法。對雙側(cè)壁導(dǎo) |
