英文摘要	Experiments are conducted to investigate the creep and hydraulic behaviours of single fractured granite under hydro-mechanical condition. The results show that, both the axial strain and lateral strain develop with time. Axial strain becomes stable after the early hundreds hours, while lateral strain of seepage sample always increases during the whole experiment time. It is concluded that hydraulic pressure greatly influences the lateral strain variation, which shows some special properties that are different from the common traxial creep curve. Based on the test, anisotropy elastic-visco-plastic creep model is established, which is integrated into a 3D cellular automaton modeling system (EPCA(3D)-EVP). With this system, anisotropy creep characters of fractured rock under test condition can be well modeled.
