Abstract

The invention belongs to the technical field of near-field micro-seismic signal processing, and discloses a near-field micro-seismic signal waveform analysis method and device, equipment and a storage medium. The method comprises the following steps: acquiring a near-field micro-seismic signal of a monitored area, and obtaining a micro-seismic signal time domain waveform of the monitored area; performing waveform processing on the microseismic signal time domain waveform to generate a microseismic signal time domain standardized waveform; extracting a maximum value of the standardized waveform, and generating a target microseismic signal time domain waveform marking a peak point; determining a starting point and an ending point of a time domain waveform section according to the time domain waveform section of the time domain waveform of the target microseismic signal; and according to the time domain waveform section and the starting point and the ending point of the time domain waveform section, generating a linear segmentation fitting curve of the time domain waveform of the target micro-seismic signal, and finally analyzing the linear fitting curve through a preset data model to obtain a representation form and an analysis result of the time domain waveform of the micro-seismic signal, and therefore, the generality and the difference of various micro-seismic signals are obtained.

Description

technical field [0001] The present invention relates to the technical field of near-field microseismic signal processing, in particular to a method, device, equipment and storage medium for analyzing waveforms of near-field microseismic signals. Background technique [0002] Microseismic monitoring is a commonly used geophysical detection technology in the field of geotechnical engineering. This technology is used to collect vibration data generated by rock mass rupture induced by engineering activities in real time. In the early days, microseismic monitoring was mainly used in the fields of mines and oil and gas exploitation. With the implementation of the national strategy of "going deep into the earth", a large number of deep high-stress projects emerged in the fields of national defense, water conservancy and hydropower, underground laboratories, and transportation. It has played a prominent role in stress disaster monitoring and prediction and early warning, and has be...
