Cette thèse a pour objet l'étude des invariants de type fini des sphères d'homologie rationnelle de dimension 3, et des nœuds homologiquement triviaux dans ces sphères. Les principaux résultats sont présentés dans le chapitre 2. Ils sont démontrés dans les chapitres 3 à 6. Le chapitre 3 est un article intitulé ``Finite type invariants of rational homology 3-spheres'', à paraître dans Algebraic & Geometric Topology. Il décrit le gradué associé à la filtration de l'espace vectoriel rationnel engendré par les sphères d'homologie rationnelle, définie par les chirurgies rationnelles préservant le lagrangien. Le chapitre 4 est un article intitulé ``On Alexander modules and Blanchfield forms of null-homologous knots in rational homology spheres'',...
