| 連拱隧道地形偏壓臨界覆土厚度的研究(49 卷) |
| 英文標題 |
| Study on critical overburden thickness in terms of terrain biased pressure acting on continuous-arched tunnel |
| 摘要 |
| 對于偏壓連拱隧道，最新公路隧道設計規(guī)范雖然在其附錄中給出了偏壓隧道襯砌荷載的計算方法，但沒有指出何種情況下按偏壓隧道襯砌荷載計算。借鑒鐵路隧道設計規(guī)范的經(jīng)驗，應用比爾鮑曼理論求得塌落拱曲線方程，然后用作圖法在連拱隧道外側作一個切線與以地形的坡度求出的塌落 |
