摘要:
 以不同水泥掺量的湖南黏性土为研究对象，通过土-水特征曲线试验（滤纸法）研究水泥掺量对持水性能的影响。随着水泥掺量的增加，试样的持水性能逐步增强。基于实测水泥土土-水特征曲线数据，利用VG模型和Gardner模型对其进行拟合，比较不同模型的拟合效果。结果表明: 水泥掺量在8%～20%范围内，随着水泥掺量的增加，在同等吸力条件下试样对应的含水率越高；与VG模型相比，Gardner模型的拟合结果与实测值更为接近，拟合的效果要优于VG模型。
Abstract:
 Taking Hunan clay-soil with different cement content as the research object, soil-water characteristic curve test (filter paper method) was carried out to study the effect of cement content on water holding capacity. With the increase of cement content, the water holding capacity of the samples gradually increased. In addition, based on the measured cement soil-water characteristic curve data, the VG and Gardner model are used to fit it, and then the fitting effects of different models are compared. As the studies show: The cement content is in the range of 8% ~ 20%. With the increase of the cement content, the higher the water content of the sample under the same suction condition. The fitting results of the Gardner model are closer to the measured values, and the fitting effect is better than the VG model.
