Abstract A new strength estimation equation for cement-treated clay is proposed for marine clay with wide ranges of sand and initial water contents. The proposed equation can determine the strength of cement-treated soil by using two parameters, the ratio of the cement content to the mass of fine particles in the soil and the volumetric solid ratio excluding sand, where sand is defined as particles greater than 0.075 mm. A series of strength tests was performed on cement-treated soil with various sand, cement, and initial water contents. From the test results, it was found that the strength of cement-treated clay is primarily determined by the ratio of the water and cement contents to the fine-grained soil and was not related to the sand particles. The applicability of the proposed equation was compared to that of the existing three strength estimation equations. The proposed equation demonstrated the best fitness between the measured and the estimated strengths of marine clays with the wide ranges of sand and initial water contents.

大范围砂子和初始含水量的水泥处理海相粘土强度估算

摘要 针对含砂量和初始含水量范围较广的海相粘土，提出了一种新的水泥处理粘土强度估算方程。所提出的方程可以通过使用两个参数来确定水泥处理土壤的强度，即水泥含量与土壤中细颗粒质量的比率和不包括沙子的体积固体比，其中沙子定义为大于 0.075 毫米的颗粒. 对不同砂、水泥和初始含水量的水泥处理土进行了一系列强度试验。从试验结果发现，水泥处理粘土的强度主要取决于细粒土中的水、水泥含量比，与砂粒无关。将所提出方程的适用性与现有三个强度估计方程的适用性进行了比较。所提出的方程证明了具有广泛范围的沙子和初始含水量的海洋粘土的测量强度和估计强度之间的最佳拟合。
