| Abstract: | Rayleingh waves,which usually represent the most energetic part of vibrations generated during civil engineering working, are very sensitive to soil conditions.According to the shapes of Rayleigh waves from synthetic seismograms,this paper analyses the effects of soil parameters on the dispersion curve of Rayleigh wave and presents the method for testing shear wave velocity by Rayleigh wave, in which the testing technique Rayleigh wave is investigated and the disturbances of noise,non-linearity of system and the other man-made factors are removed using correlation analysis theory. In the end,combining the examples,the authots demonstrate the feasibility of the above mentioned method in seismic survey and point out some problems which should be further improved. |
