Concept de vulnérabilité appliqué à l'évaluation des risques générés par les phénomènes de mouvements de terrain

Abstract : This thesis is in keeping with a global outlook on the perception help of the risk induced by ground failures phenomena. The approach privileged in this work is the analysis of vulnerability concept, a fundamental but not very explored component of risk appraisal. In a first time, the application of this concept to ground failures phenomena requires to structure its different components and to define it in accordance with a theoretical definition of risk and taking of decisions compatible with a quantitative assessment approach. In a second time, different back analyses are carried out on recent cases. The aim is first to stress the importance and diversity of the damage generated by ground failures, and then to obtain various information necessary to elaborate such assessment methodology. This methodology is then developed and afterwards illustrated through two applications. It's based on the notions of exposed elements and phenomena solicitation intensity. It's structured by means of matrices of damage. Such matrices contribute to give a homogeneous framework of the quantification of elements-phenomena interaction. Finally, the aim of this methodology is to confront risk managers to scenarios resulting from phenomenon manifestation. This methodology can be reproduced and its principle transposed to other types of natural phenomena.
