摘要
杭州轨交1号线闸—火区间联络通道在临近的轨交4号线官河站基坑施工过程中发生不均匀沉降。为达到抬升隧道、恢复隧道正常使用功能的目的,修复措施采用隧道底部压密注浆技术。结合工程实际,分析了相应的压密注浆控制措施,并提出了压密注浆控制的几点建议,供类似工程参考。
Uneven settlement occurred in the connection passage of Zha-Huo interval tunnel of Hangzhou Rail Transit Line 1 while the neighboring excavation pit of Guanhe Station of Rail Transit Line 4 was built. To uplift the connection passage and restore its normal function,compaction grouting was implemented at the bottom of connection passage. Combined with the engineering practice,the corresponding compaction grouting control measures are analyzed,and some suggestions are given for similar engineering reference.
