基于最近公布的确定性的解决方案作为基准，随机有限元法在这里被用来调查的空间变异性的影响正常固结随机边坡的不排水稳定性，其中的平均强度随深度线性增加，而变异系数保持不变。结果以图表的形式呈现，给出了无量纲稳定数的平均值和标准差。使用本说明中提供的图表，工程师可以对正常固结粘土边坡的破坏概率进行初步评估。
Based on recently published deterministic solutions as a benchmark, the random finite-element method is used here to investigate the influence of spatial variability on the undrained stability of normally consolidated random slopes, where the mean strength increases linearly with depth while the coefficient of variation remains constant. Results are presented in the form of charts that give the mean and standard deviation of a dimensionless stability number. Using the charts presented in this note, engineers can obtain a preliminarily assessment of the probability of failure of normally consolidated clay slopes.
