Popis:	This is a report on a study of parameters identification of mechanical constants of anisotropic rock mass and initial ground pressure from set of displacements on assumption that rock mass is anisotropic continuous elastic medium, and applicability of this method to excavation control of underground openings are also shown. A local iterated extended Kalman filter of control theory combined by Finite Element Method are applied to the parameter identification method in order to consider probabilistic feature of measured datum.It is concluded that this identification method is effective for excavation control of underground openings excavated in anisotropic rock mass.
