摘要: Pour mieux comprendre le phenomene des «vagues de pression», on etudie la stabilite shelfs aux perturbations champs moyens contrainte et vitesse deformation. L'analyse est basee sur loi fluage Glen. On montre que si les vitesses deformation sont suffisamment compressives, peut s'attendre a voir apparaitre ondulations. Les extensions laterales ont un effet stabilisateur vagues pression plus chance se former lorsqu'elles existent
