【摘要】探讨了有关河谷岩体地应力的一些认识及地应力场模拟的方法,提出应力场的模拟需要考虑区域地应力条件及河谷发育过程两个因素的作用,及采用正交回归设计和三维有限元相结合的数值模拟方法的可行性,并将其应用于某电站地下厂房岩体三维地应力场的计算和评价。更多还原

【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.更多还原
