Application of Geophysical Techniques for the Diagnosis of Underground Conditions Promoting Distress - Case Study

Integration of Geophysical techniques with Geotechnical techniques (Drilling of Calibration boreholes) lead to that definitive answers regarding subsurface conditions were provided to the end users: • Defining the scope of the site problem pointing to adverse strata and hazardous ground conditions. • Guidance to diagnosis of Ground Conditions Promoting Distress • Recommendation for the safety design and construction of engineering structures with or without the mitigation procedures for ground improvement. In this study the recent geophysical techniques used in civil engineering investigations and its integration into the overall geotechnical information in relation to detailed design, Road & Building construction, are discussed and illustrated with three case histories.
