Notes:
In this paper, a new concept, YAI (yielding approach index), is firstly proposed to estimatethe safety differences of rock and rockmass whose stress states are close to yielding. Secondly, inorder to describe the intrinsic heterogeneity of strength of the same rock, the safety parameter ω,which is the phase complementary parameter of YAI, is supposed to be a stochastic variable in thispaper and conform to the Weibull’s distribution. By analyzing the triaxial test data of five types ofrocks, it can be found that ω as a stochastic variable evidently conforms to the Weibull’s distribution.Results in this paper give an important and useful reference to the safety analysis for geotechnicalengineering
