| 軟弱地層地鐵折返線段施工方法數(shù)值模擬研究(51 卷) |
| 英文標(biāo)題 |
| Numerical simulation study on tunnel construction method in metro back-turning section at soft soil zone |
| 摘要 |
| 通過對(duì)某地鐵折返線建立FLAC三維數(shù)值計(jì)算模型，研究了CRD法、CD法、無仰拱臺(tái)階法、有仰拱臺(tái)階法等不同的施工方法和不同的初期支護(hù)參數(shù)對(duì)地表位移、圍巖應(yīng)力、初期支護(hù)受力等的影響，并據(jù)此選擇最優(yōu)的施工方法。 |
