Application of SSP Seismic Scattering and Geological Radar in Foundation and Subsurface Obstacle Detection

With the continuous development of urban construction, in order to ensure the smooth progress of the construction process, it is usually necessary to treat the foundation, so it is necessary to test the mechanical properties and lithology of the foundation strata and underground obstacles. In this paper, SSP seismic scattering technology and geological radar method are used to detect the foundation of the starting well of the Comprehensive pipe gallery project in Chengbei Road, Suzhou City. SSP seismic scattering technology comprehensively utilizes reflection and scattering seismic data to perform fine imaging of geology, which can be used as a basis for judging the mechanical properties of geotechnical media. It can identify difficult geological objects such as karst, boulder, grouting and goaf. The geological radar can comprehensively scan the underground obstacle target, obtain the vertical two-dimensional section image of the cross section, and judge the actual structure of the underground target. Both detection methods have advantages, and depending on the situation, the appropriate detection method can be chosen.
