通过收集整理大量尾矿坝资料，基于概率分布假设检验及可靠性截断概率，建立了不同矿种尾粉土物理力学参数的最优概率分布模型，提出了各类物理力学参数的合理取值范围，并对尾粉土的物理力学性质进行了对比分析。结果表明，尾粉土物理性质参数变异系数较小，稳定性较好，但力学性质参数的变异系数较大，离散性较高；不同矿种尾粉土的物理力学参数大都符合正态分布或对数正态分布的最优概率模型；以68%的置信概率作为可靠性截断概率，给出了尾粉土各物理力学参数的建议取值范围，为尾矿库的可靠性设计及细粒尾矿工程的特性研究提供了重要参考。

Through sorting out a large amount of mine tailings data and based on the probability distribution hypothesis test and truncation reliability probability, an optimal probability distribution model for different silty soil tailing's physical and mechanical parameters were established, the reasonable value range of parameters were put forwarded, and a comparative analysis on physical and mechanical properties of the silt soil tailing was carried out. The results show that the variation coefficient of physical parame-ters is small, but the mechanical parameters are characterized as opposite features. The physical and mechanical parameters of different mineral tailing silt mostly accord with the optimal probability model of normal distribution or lognormal distribution. Tak-ing 68% confidence probability as the truncation reliability probability, the value ranges of physical and mechanical parameters of silt tailing were recommended, which can provide significant important references for the reliability design of tailings project and engineering properties research of fine-grained tailings.
