| 英文標(biāo)題 |
| Analysis on ground surface settlement induced by urban metro shield tunneling |
| 摘要 |
| 地層損失是盾構(gòu)施工產(chǎn)生土體變形的主要原因。以成都地鐵1號(hào)線某盾構(gòu)區(qū)間隧道為工程背景，根據(jù)現(xiàn)場(chǎng)前期監(jiān)測(cè)結(jié)果，提出了基于地層損失概念的“約束—釋放”法來模擬土壓平衡盾構(gòu)開挖過程，運(yùn)用三維有限差分模型對(duì)不同地層損失量下的地表沉降橫向分布和地表土層水平橫向應(yīng)變進(jìn)行 |
