Analysis of coupled seepage and stress firelds in rock mass by considering hydrodynamic seepage pressure

Permeable pressure in fractured rock mass indeed changes stress in rock,at the same time the change has influence on permeability of fractured rock mass.Coupling analysis of seepage and stress is the main problem to researching groundwater floating laws.When the fracrues is the main character and distribution is intensive,the rock is considered as equivalent continuous polyphase medium.With equivalent continuous medium theory,a model of seepage and stress coupling effect in equivalent continuous rock is built and the influence that existence of permeable pressure and fracture has on rock stress and water pressure in pore and fracture is sufficiently considered.In the end,acalculation example of a project for coupling analysis of seepage and stress is given.
