9 QUAL I TÉ GÉOPHYSIQUEAPPLIQUÉE Foreword 1 J.-L. Mari, C. Vergniault Based on their experience in geophysics applied to the oil and gas industry and the geotechnical field, the authors have set out to explain how conventional approaches used in deep exploration geophysics can be applied to certain geotechnical and hydrogeological surveys, and site characterizations in the framework of seismic hazard studies. After reviewing the current state of knowledge in the geotechnical field regarding borehole measurements of subsurface shear velocities, the book aims to illustrate the feasibility of carrying out vertical seismic profiles, logs and 3D seismic reflection blocks. In addition to these examples, the authors have sought to provide readers with guidelines to carry out these operations, in terms of acquisition, as well as processing and interpretation. The authors thank Françoise Coppens, Patrick Meynier and Gilles Porel for their contributions to this book.
