- Abstract
Debris-prone areas are widely distributed worldwide, all continents except Antarctic have been harmed by debris flow. Debris flow normally outbreaks all of a sudden, sweeps along fast accompanying with other disasters like landslides, flood and collapse. It has huge destructive power, making severe threats to water conservancy and hydropower, mines, traffic in mountain areas and other engineering facilities as well as local people’s lives, property and safety.This task makes an in-depth research on theory of infrasonic wave produced when debris flow occurs. Infrasonic signal collected in the experiment has been transformed with Hilbert-Hang (HHT) which is good at analysis and processing of nonlinear and unstable signals. This system enables to transform debris flow’s infrasonic signal collected with infrasonic wave sensor to digital signals by data acquisition card and send it to computer, and then analyze and process such signal using digital signal processing methods in combination of characteristics of infrasonic signal. This research makes an efficient separation of infrasonic signals which are produced by debris flow and environment noises. So in this way, a debris flow monitoring system can be designed based on infrasonic wave.
