WANG Tao, ZHOU Xian-qian, TIAN Shu-bin, et al. Numerical simulation method for rock natural stress field of a valley and its application based on orthogonal experiments[J]. 2003, 24(5).DOI:
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.
