摘要
文章介绍了大伙房水库输水工程TBM1施工段26+960-27+691洞段围岩发生塑性变形、侵占设计断面的处理措施,同时设计布置了永久性监测仪器。通过对仪器采集数据等相关资料的科学分析,表明该段隧洞围岩处于稳定状态。
According to the plastic deformation and encroaching the design section for surrounding rock in 26+ 960-27+691 length of TBM1 construction for water conveyance project of Dahuofang reservoir, the paper introduces these treatment measures and designs and layouts the permanent monitoring instruments. By scientifically analyzing the collecting data on equipment and other related information, the result shows that the tunnel surrounding rock is stable.
