重庆库区松散土体物理力学参数的数理统计分析

Symbolic stat analysis to physical and mechanic parameters of loose earth in Chongqing reservoir

岩土物理、力学参数最重要的性质是具有复杂的空间变异性和明显的不确定性 ,笔者将岩土的物理力学参数视为具有随机性和结构性特征的变量入手 ,运用数理统计方法对岩土的物理力学参数进行分析 ,统计结果显示 。

On the basis of testing in Lab to loose earth in Chongqing reservoir,the authors present probability analysis of earth characteristics including physical and mechanic parameters,then propose and test the distributions of the characters.The results verify that interior friction angle φ obeys logarithm normal distribution while cohesion c,unit weight r and water ω obey normal distribution.Therefore,sensitive parameters testing in Lab are reliable.
