A coupled hydro-mechanical modelling of CO2 injection into deep aquifers is proposed. Multiphase and multicomponent fluid flow is considered in interaction with the rock geomechanical behaviour. The numerical methods used to link a flow transport code and a mechanical code, in particular fields transfer between non-coincident meshes and time coupling algorithm, are then presented. Some results of large scale simulations especially some aspects of the mechanical integrity of caprock are finally discussed
