Design of Acoustic Emission Monitoring Host Machine for Landslide Mass Critical-sliding
Honghui Wang · Automation and Instrumentation · 2011
According to the acoustic emission characteristics of rock fracture and friction in the time of landslide mass critical-sliding,presents an early warning system for landslide mass critical-sliding based on acoustic emission monitoring this paper.The monitoring acoustic emission frequency range is 1Hz～20kHz,minimum acoustic pressure is 0.002Pa.By putting the pressure field acoustic emission sensor around the landslide mass,the system can monitor and record continuously the acoustic emission produced by critical-sliding landslide mass.These acoustic emission data can be used to study its characteristics and change rules,and realize the prediction of landslide disasters.
