Study on the key technology of probing urban active faults by shallow reflection method with anti-disturbance high resolution
The significance of urban active fault detecting and its basic developing situation are introduced briefly. Based on the simple describle of the basic principle of anti-disturbance high-resolution shallow seismic exploration, All the sources,the properties of digital seismic instruments, the receive method and conditions, the observation system,and the data processing and interpretation of the urban active fault detecting are discussed emphasizedly. The research results are that the controlled source which has linear or nonlinear variabe frequency scan function and the seismic instruments which match with it,and the method of small group intervals, small offset, much more channels, short array length, high-frequency receivers are applied during the link of data acquisition, and that the techniques of the refraction static correction, the noise suppressing, the high-resolution velocity analysis, the wavelet length compression, the wavelet zero-phase, and the prestack migration should be applied emphasizedly during the link of data processing and interpretation. finally, an field example is given.
