摘要
在地下工程巷道中,利用监测技术可以预测未开挖部分的围岩变形,监控巷道变形和支护的稳定性,具有不可忽视的作用。文中研究了地下工程巷道现场监测方法,分析了必测项目的监测内容,并建议应该建立完整的监测方案和围岩失稳预警机制,来监测巷道的变形趋势,对地下工程巷道监测技术具有一定的指导意义。
In the underground construction roadway, the use of monitoring technology can predict no-work ing part of deformation of surrounding rock, the role of roadway deformation monitoring and stability sup porting can not be ignored. This paper studies the monitoring method of underground roadway site, analyses the monitor content tbat must be measured, recommends a complete monitoring program and rock fail ure warning mechanism should be established to monitoring the trends of roadway deformation. It isacer tain guiding significance to technology of monitoring underground construction roadway.
