陈达力 %J 岩石力学与工程学报 %D 1994 %I %X This papaer describes rock ultrasonic spectrum measurement technology. That is to adopt narrowpuise emissiom,broadband receivation and microcomputer analysis system;to take sound wave propagation characteristics and size effects into accownt of the samples during experiment;to discretize andquantize sound signs for data precessing;to take effective waves of rock characteristics by digital technology for fourier transform to obtain rock frequency spectrum,and to employ ultrasonic spectrum technologyfor research into rock properties-characterestics values of rock can reflect rock structure,mineral content,cementing and weathering extent etc and are relative to rock mechanics parameters,while spectrum shapecan reflect integral extent of rock. %K rocks %K acoustic wave %K spectral analysis %K basic frequency %K frequency spectrum
