【Abstract】 Seismic scattering profile(SSP) is a new seismic survey technique,which utilizes the scattering wave generated by the heterogeneity of the underground mediums to image the geological structures.The images are of high resolution,intuitive and suitable for engineering applications.The application of SSP in tunnel collapse geological survey has achieved satisfactory results.The identification of the geological reasons and extent of the diseases are examined,which provide the reliable basis for the risk management in tunnel construction.The practical application shows that the SSP technique is suitable to survey in mountain areas or complex geological areas.更多还原
