This study deals with the variation in strength of clays stabilized by a special binder—the CEM II/B-V type of Portland-fly ash cement. Two sources of uncertainties were examined, that is, the uncertainty in cement fraction in the binder, and the nonuniformity in binder concentration resulted from the process of mixing binder slurry with in situ clays. These two uncertainties were quantitatively described as two random variables, and the analyses were conducted through the Monte Carlo simulation method. Results indicate that the strength is insensitive to the cement fraction in the binder but is sensitive to the binder concentration; the variation of the latter even results in an amplified variation of strength. The variation of binder concentration is proposed to be linked up with the variation of strength through the operational parameter of blade rotation number. By doing so, the results could benefit designers in quality control prior to the construction of soil stabilization.

统计量化一种波特兰粉煤灰水泥稳定的海相粘土强度的不确定性

这项研究解决了由特殊粘结剂（CEM II / BV型波特兰粉煤灰水泥）稳定的粘土强度的变化。检查了两个不确定性来源，即，粘合剂中水泥含量的不确定性，以及粘合剂浆液与原位粘土混合过程导致的粘合剂浓度不均匀性。将这两个不确定性定量地描述为两个随机变量，并通过蒙特卡洛模拟方法进行了分析。结果表明，强度对粘合剂中的水泥含量不敏感，但对粘合剂浓度敏感。后者的变化甚至会导致强度的变化。建议通过叶片转数的操作参数将粘合剂浓度的变化与强度的变化联系起来。这样一来，结果可以使设计师在建造土壤稳定层之前进行质量控制。
