Abstract


3 d seismic prospecting methods in urban system in the field of engineering survey is less, especially in the domestic application is almost blank. To check 3 d seismic exploration method application in the urban engineering investigation results, this paper selected a Shanghai high school playground as the experiment site, has carried on the preliminary attempt to three-dimensional seismic exploration method. The research of this paper is focused on the shallow 3 d seismic data processing link in seismic exploration, research is focused on the shallow 3 d seismic data denoising before stack, amplitude compensation, deconvolution techniques. Through a lot of experiments and processing parameters module choice experiment, finally obtained a set of applicable to the work area of shallow data processing process and processing parameters. After processing of 3 d after stack profile in a shallow reflector, wave group characteristics, waveform is stable and continuous tracking. Finally, using the method of 3 d display has made the simple data interpretation. The paper research results show that 3 d seismic exploration in city engineering investigation is feasible in application, and can obtain good exploration result.
