摘要
针对TBM开挖工作面实施微震监测过程中存在的空间狭窄、钻孔不便、线缆易损等诸多困难,为了实现微震监测系统的稳定运行,确保数据采集的连续性、完整性和数据传输的实时性,在引汉济渭工程秦岭输水隧洞越岭段3号支洞的TBM开挖工作面,经过多次数据比对、优化改进,摸索出一套更适合TBM开挖工作面开展移动式微震监测的系统构建方案。通过6个月的连续监测表明:使用该方案,监测系统与TBM彻底分离,互不影响,正常供电时数据连续采集率为100%;数据传输稳定可靠,外部网络正常时仅有1 d因路由器供电故障而导致数据无法传输,故障率为0.55%;传感器线缆没有出现意外损坏,故障率为0,为岩爆风险预测提供了充分的数据保障。
For TBM excavation working face in the process of implementation of micro-seismic monitoring the space is narrow , borehole in-convenience vulnerability , cables , data transmission and many other difficulties , in order to realize the stable operation of the micro-seismic monitoring system to ensure the continuity of data acquisition , integrity and the real-time performance of data transmission , in No.3 tunnel TBM excavation working face of Hanjiang-to-Weihe River Water Diversion Project , after several data comparison and optimization improve-ments , it had figured out a plan that was more suitable for building mobile fading earthquake monitoring system in TBM excavation working face. Through continuous monitoring for 6 months , it is shown that the monitoring system is completely separated from TBM without affecting each other. When the power supply is normal , the continuous data acquisition rate is 100%. Data transmission is stable and reliable. When the external network is normal , the data cannot be transmitted due to the power failure of the router for only 1 day , so the failure rate is 0.55%. There is no accidental damage to the sensor cable and the failure rate is 0 , which provides sufficient data support for rock burst risk prediction.
