摘要依托金川水电站泄洪洞工程,引入微震监测技术实时在线监测围岩变形破坏,研究泄洪洞围岩微震事件的时空演化特征,采用横纵波能量比E_S/E_P对金川水电站泄洪洞围岩破裂机制进行研究,将分形-岩石力学理论引入微震监测领域,分析微震在时间和空间上释放能量的分形维数演化规律。通过对分形维数的演化规律,现场勘察和常规监测数据进行比较分析,揭示分形维数与围岩在时间和空间上的大变形之间的关系:在变形发生前岩体的微震能量分形维数在时间和空间上都会出现降维现象,这可以作为预警前兆信号。

Abstract: Based on the spillway tunnel project of Jinchuan Hydropower Station, this research introduced the microseismic monitoring technology to monitor the deformation and failure of surrounding rock in real time, and studied the spatio-temporal evolution characteristics of microseismic events in surrounding rock of spillway tunnel. The failure mechanism of surrounding rock in spillway tunnel of Jinchuan Hydropower Station was analyzed by means of energy ratio of transverse and longitudinal waves E_S/E_P. The fractal rock mechanics theory was introduced into the field of microseismic, and the spatiotemporal evolution of the fractal dimension of energy released by microseismic was analyzed. The relationship between the fractal dimension and the deformation of surrounding rock in time and space was revealed through the comparative analysis of the evolution law of the fractal dimension and conventional monitoring data. The fractal dimension of the microseismic energy of rock mass before the deformation occured would appear dimension reduction in time and space, which could be used as a warning signal.

Key words: microseismic monitoring failure mechanism fractal rock mechanics fractal dimension
