| 盾構(gòu)在道路和鐵路下推進(jìn)引起的沉降對(duì)比研究(50 卷) |
| 英文標(biāo)題 |
| Comparative study on settlement induced by shield-driving tunnel under highway or railway |
| 摘要 |
| 以天津市津?yàn)I輕軌西段地下線工程為背景，對(duì)盾構(gòu)施工引起的道路及鐵路地表沉降數(shù)據(jù)作了詳細(xì)的對(duì)比研究，得出了地表縱向和橫向沉降規(guī)律，闡述了盾構(gòu)下穿道路和鐵路時(shí)引起周圍環(huán)境變化的異同點(diǎn)。應(yīng)用Peck公式反演了盾構(gòu)過道路段的地層損失率，提出了地層損失率限值。 |
