盾构隧道穿越复杂敏感建筑群施工关键技术分析

Key Technology of Shield Tunnel Passing Through Complex Sensitive Buildings

文中以嘉兴市域外配水工程下供水隧道工程D4-1井~D5井盾构区间工程为背景,基于该项目涉及穿越沪昆铁路上行线2股道和杭州北车辆段17股道(含道岔)的情况,提出了详细的盾构下穿期间的沉降控制措施,最终经过分析可知,采取的沉降控制措施有效。

Based on the shield interval project of well D4-1~ D5 of water supply tunnel project of Jiaxing External water distribution Project,and the situation that the project involves crossing 2 tracks of Shanghai-Kunming railway upstream line and 17 tracks(including the turn) of Hangzhou North vehicle section, the detailed settlement control measures during the shield tunneling are put forward. The final analysis shows that the settlement control measures are effective.
