在断层破碎带、岩爆、涌水、膨胀岩等不良地质地带施工时常常容易发生TBM被埋、被淹、被卡事故。本文提出利用微地震监测技术监测隧道围岩或岩体破裂,从而了解TBM前方地质情况,做好工程处理措施以避免事故发生。介绍了微地震监测技术理论依据及发展情况,重点说明微地震监测系统的现场布置和关键技术,分析并阐述微地震技术在现实监测中的可能性及应用前景。 In the fault zone, rock burst, gushing water, expansive rock and other adverse geological construction is often prone to TBM buried, flooded, card accident. In this paper, microseismic monitoring technology is used to monitor the surrounding rock or rock mass rupture, so as to understand the geological conditions in front of the TBM and do engineering measures to avoid accidents. The theoretical basis and development of microseismic monitoring technology are introduced. The field deployment and key technologies of microseismic monitoring system are described emphatically. The possibility and application prospect of microseismic technology in actual monitoring are analyzed and explained.
