摘要
针对以往的岩土强度参数分布拟合中,将强度参数中的2个强度参数f,c分开来进行拟合,忽略了二者间高度相关性的问题,采用二维正态分布来对岩土强度参数进行联合分布拟合研究,并通过岩滩水电站中结构面抗剪强度参数的分布拟合验证了该法的可行性.
In the geotechnical engineering, the probability distribution of geotechnical strength parameters（f, c） is the base to determine the geotechnical parameter value. In the past analysis, geotechnical strength parameters （f, c） is researched independently and then the correla- tion between geotechnical strength parameters is ignored. Geotechnical parameters can be researched with two-dimension probability distribution, and the sample of the Yantan hydropower station is used to prove the feasibility of this method.
