随着胶结剂稳定软土技术的日益普及，胶结粘土强度随龄期的准确预测对质量控制具有重要意义。本文提出了一种广义双曲函数，克服了传统对数函数对强度发展的短期和长期预测的不足。广义公式也可适用于各种水泥类型、土壤类型和养护条件。结果表明，该模型适用于普通硅酸盐水泥（OPC）和硅酸盐高炉水泥（PBFC）处理的粘土。该模型还可用于胶结粘土的刚度预测。基于该模型预测的胶结粘土强度和刚度与文献实测数据具有较高的一致性。
With the increasing popularity of stabilizing soft soils by a cementitious binder, accurate strength prediction of cemented clay with curing period is essential for quality control. In this study, a generalized hyperbolic was proposed to overcome the shortcomings of traditional logarithmic function with regard to both short-term and long-term prediction of strength development. Also, the generalized formula can be used for various cement types, soil types, and curing conditions. It was proved that the model works well for both Ordinary Portland cement (OPC) and Portland blast-furnace cement (PBFC) treated clay. Moreover, the model can also be adopted for stiffness prediction of cemented clay. Based on the proposed model, the predicted strength and stiffness of cemented clay shows high consistency with the measured data from previous literature.
