| 超大型泥水盾構(gòu)水中接收施工技術(shù)(50 卷) |
| 英文標(biāo)題 |
| Construction technology of receiving super-large slurry shield under water |
| 摘要 |
| 對(duì)于大型泥水盾構(gòu)，由于其掌子面的保壓特性，在破洞門時(shí)必然造成內(nèi)外壓力失衡，易造成盾構(gòu)與洞門圈間隙涌泥涌砂及地表沉降事故。南京長(zhǎng)江隧道工程采用水中接收技術(shù)，確保了洞內(nèi)外壓力平衡；另外在盾構(gòu)接收地段，采用了三軸攪拌加固、冷凍加固、強(qiáng)降水三重措施，確保盾構(gòu)接收 |
