ROCK-BED SLOPE STATE DETERMINATION SYSTEM AND ROCK-BED SLOPE STATE DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a rock-bed slope state determination system and a rock-bed slope state determination method for analyzing waveform data of AE (Acoustic Emission) in a short time without wrong determination, and executing automatically accurate rock-bed state determination.;SOLUTION: This rock-bed slope state determination system for evaluating/determining the state of a rock-bed slope which is an inspection object from analysis of the waveform data sensed by an AE sensor 4a installed on the rock-bed slope R, includes an AE signal discrimination unit 7 for discriminating an output signal from the AE sensor 4a between an AE wave and another signal, a frequency determination unit 8 having a frequency determination means of the AE wave using a center-of-figure method, and an analysis determination unit 9 for determining the state of the rock-bed which is the inspection object based on transition of the generation number of the discriminated AE waves and on a frequency change of the AE wave determined by the frequency determination unit.;COPYRIGHT: (C)2009,JPO&INPIT
