Abstract: The rock mass natural stress of a valley and methods of simulating natural stress field are discussed. The authors recognize that the two factors, regional natural stress condition and the course of valley development, should be considered. The means of combining orthogonal experiment theory with FEM is also discussed through a multi-faceted approach from its feasibility and evaluation angles, and it is applied to computing and evaluating the 3-D natural stress field; of an underground power house of a hydropower station.

Key words: natural stress, orthogonal experiment, FEM
