It occurred a large-scale landslide in the Three Gorges Reservoir, Qianjiangping village, shazhenxi town, Zigui County on July 13, 2003, causing serious economic losses and casualties. The digital telemetry seismic network in the Three Gorges Reservoir recorded a complete landslide sliding process of ground vibration, and obtained five micro-fracture events in the vicinity of its margin clearly before the landslide occurred. After a waveform comparison with tectonic earthquakes, mine earthquake signal and so on, we analyzed Qianjiangping landslide, micro fracture signal waves, spectral parameters and energy time-frequency distribution characteristics. It shows that pre-five micro-fracture signal waveforms are similar to the waves of landslide, but the spectrum parameters and the energy time-frequency distribution of pre-five micro-fracture signal are similar to a tectonic earthquake. Extracting and recognizing previous micro fracture characteristic signals of large-scale landslide with seismic network records, has an important theoretical significance and practical value for landslide early warning research.
