Nous étudions des limites de grande échelle de systèmes de particules en interaction. Dans chaque modèle, nous considérons des systèmes à N particules en interaction champ moyen avec une force d'interaction aléatoire et centrée de l'ordre de N^{-1/2}, et démontrons la convergence de ces systèmes quand N tend vers l'infini. Dans le cadre plus classique où la force des interactions est N^{-1}, on constate une propagation du chaos. Dans notre cadre, nous montrons des propagations du chaos conditionnelles. Nous étudions trois types de modèles. D'abord, nous étudions des systèmes de processus de Hawkes dont nous montrons la convergence des intensités stochastiques. Comme ces intensités sont, dans notre cadre, des processus de Markov, nous montro...
