Le probl\u00e8me des chargements diff\u00e9r\u00e9s sur le sout\u00e8nement des tunnels, et des effets d\u2019\u00e9coulement d\u2019eau, sont des probl\u00e8mes d\u2019un grand int\u00e9r\u00eat pratique mais relativement peu abord\u00e9s en raison de leur complexit\u00e9 surtout en mode hydrom\u00e9canique coupl\u00e9 qui n\u00e9cessitent de grands temps de calcul. Dans ce travail, on examine la possibilit\u00e9 de prendre en compte le r\u00f4le de l’eau dans une approche simplifi\u00e9e, qui se ram\u00e8ne \u00e0 un calcul m\u00e9canique classique. Pour autant, une approche d\u00e9coupl\u00e9e pr\u00e9sente l’avantage d’\u00eatre extr\u00eamement simple \u00e0 mettre en \u0153uvre, et elle permet d’aborder, si l’on se contente d’un calcul \u00e9lastique en premi\u00e8re analyse, des ph\u00e9nom\u00e8nes complexes, comme la redistribution des contraintes sur le rev\u00eatement d’un tunnel lors d’une r\u00e9paration partielle. Donc, on pr\u00e9sente une \u00e9tude num\u00e9rique de l\u2019effet de l\u2019\u00e9coulement d\u2019eau sur un tunnel circulaire \u00e0 l\u2019aide du code de calcul num\u00e9rique explicite Flac2D et Flac3D. Cette \u00e9tude montre que la mod\u00e9lisation num\u00e9rique peut permettre de fournir des \u00e9l\u00e9ments de r\u00e9flexion int\u00e9ressants.<\/p>\n
