应用岩土工程可靠度计算中常用的一次二阶矩（ＦＯＳＭ）法，以ＭｏｈｒＣｏｕｌｏｍｂ准则的抗剪强度参数ｃ，φ为例，针对各种不同分布函数概型对可靠度指标的敏感度进行了定量分析。结果表明，岩土工程可靠度计算中分布函数概型引起的可靠度误差不容忽视。
Application of the first order second moment (FOSM) method commonly used in the geotechnical engineering reliability calculation and taking the shear strength parameter c, φ of the MohrCoulomb criterion as an example, the sensitivity of various distribution function profiles to the reliability index Quantitative analysis. The results show that the error of reliability caused by the distribution function in geotechnical engineering reliability calculation can not be neglected.
