Full Waveform Acoustic Logging for Slope Weak Layer Evaluation
Rock deformation and unstable failure of slope is controlled by weak structural plane whose identification and evaluation is greatly influenced by deformation failure prediction of slope and design treatment. Based on the propagation characteristics of acoustic wave in shaft lining strata, attenuation of stoneley wave and inherent attenuation of strata are analyzed and permeability relationship among shaft lining strata is researched. The relationship between reflected stoneley-wave intensity and the width and filling ability of strata crack is studied. By application example of landslide investigation, attribute parameters and characteristics of acoustic wave are discussed. Strata division, the practicability and accuracy of recognition for fracture and holes evaluation and mechanic characteristics of rock mass also are studied.
