Abstract:
Geology prediction by seismic waves, which is one of the important technical means to achieve longdistance advance geology prediction, has great significance for the safe and informationaided construction of tunnels. The development of the study on geology prediction by seismic waves, the technical performance and adaptability of the prediction instruments and devices, the requirements for the geophones and the multiwave multicomponent detections, the coupling conditions of the receiving devices and the amplitude frequency characteristics of signals, excitation means and deviations, identification and treatment of the interference waves, the analysis on the reliability of the prediction results, the contents and display means of the 3D geology prediction result maps, repeated use and comparative analysis of the signals, assessment on the parameter prediction method and the heterogeneity of the rock mass are discussed in the paper. The theoretical analysis of the technology is rational and the engineering practice demonstrates that the technology is reliable and effective. The paper can be serviced as reference for the development of the technology of geology prediction by seismic waves.
Key words: advance geology prediction, segment wave, estimated velocity, threedimensional space, multiwave and multicomponent
