【摘要】 提出了岩体Ｍｏｈｒ－Ｃｏｕｌｏｍｂ强度准则的可靠度计算方法，同时还讨论了ｃ、等强度参数的变异系数和参数概型对准则可靠度的敏感性，本文通过分析指出强度参数的变异性是准则可靠度的决定性因素之一，因此对岩体工程的详细勘察和试验以及对参数的变异性进行统计分析，对于工程设计来说是具有较大意义的。更多还原

【Abstract】 On the base of the Yirenxiang Project,the method calculating the reliability by means of the Mohr_Coulomb Empirical Strength Criterion is suggested in this paper. Furthermore,the sensibility of the variation coefficients of parameters,such as c, to the reliablilty of the criterion is discussed. Besides,the influence of the middle stress to the reliability for the Mohr_Coulomb strength criterion is analyzed and discussed.Finally,the conclusion is that the variability of the parameters is one of the determinant factors effecting the reliability of the criterion.From this paper,it is known that the detailed survey and the experiments as well as the statistic analysis are important to the technical design.更多还原
