Abstract

The invention discloses a landslide process analysis method, a process numerical reconstruction method and applications. The method for analyzing the landslide disaster process of the invention is based on the original landslide ground motion signal, extracts the IMF principal component signal, performs time-frequency spectrum transformation, and divides the landslide process into five stages according to the frequency energy characteristics in different time periods in the landslide ground motion signal. This method extracts the transition stage of the landslide process for the first time. The invention provides the application of the landslide disaster process analysis method in the landslide disaster analysis, in the design of the landslide disaster emergency response plan, and in the mathematical modeling of the landslide event. The invention also provides a method for numerical simulation and reconstruction of the landslide process, which uses the energy data evolution of the landslide ground motion signal as the basis to perform the numerical simulation and reconstruction of the landslide process. And the application of reconstruction method in landslide disaster analysis and landslide disaster emergency response plan design. Each method improves the abundance of landslide disaster basic data and the effectiveness of disaster prevention and emergency response plans, and has significant social benefits.

Description

technical field

[0001] The invention relates to a signal analysis technology, in particular to a technology for analyzing and numerically reconstructing a landslide disaster process by using ground motion signals, and its application, belonging to the technical fields of signal analysis and processing technology and geological disaster monitoring. Background technique

[0002] Earthquake observatory networks all over the world monitor and obtain massive earthquake signals every day. The essence of the ground motion signal is the seismic waveform information generated by various natural and unnatural earthquake events, including the information generated by various geological disaster events. Earthquake signal public resources, and the sharing of global earthquake information has been preliminarily realized. Therefore, the use of ground motion signals to implement various technologies for geological disaster prevention and control can greatly save the monitoring cost of geol...
