| 西安淺埋暗挖隧道地鐵施工的地表沉降分析(50 卷) |
| 英文標題 |
| Analysis of ground surface settlement in Xi’an metro tunnel drived by NATM ( New Austrian Tunnelling Method ) |
| 摘要 |
| 以西安地鐵長延堡站配線暗挖段為依托，對地表沉降實測數(shù)據(jù)進行統(tǒng)計分析。結(jié)果表明，淺埋暗挖隧道臺階法施工時上(下)導(dǎo)對一定斷面沉降的縱向影響范圍分別為其前后的2D(2D)和1D(3D)(D為隧道跨度)，且下導(dǎo)開挖所引起的總沉降量大于上導(dǎo)所引起的，其比值約為3/1；橫向影響范圍約 |
