| 英文摘要 | In this paper, a new concept, YAI (yielding approach index), is firstly proposed to estimate the safety differences of rock and rockmass whose stress states are close to yielding. Secondly, in order to describe the intrinsic heterogeneity of strength of the same rock, the safety parameter omega, which is the phase complementary parameter of YAI, is supposed to be a stochastic variable in this paper and conform to the Weibull's distribution. By analyzing the triaxial test data of five types of rocks, it can be found that omega 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 geotechnical engineering. |
