We discuss the piling of parallel cylinders with weakly fluctuating radii. The network of contacts consists of self-similar tree-like patterns. The mean expansion of the piling and the distribution of distances between adjacent cylinders are also investigated.

Nous discutons l'empilement de cylindres parallèles dont le rayon fluctue peu. Le sous-réseau des contacts consiste en des structures arborescentes auto-similaires. L'expansion moyenne de l'empilement et la distribution des distances entre cylindres sont aussi présentées.
