采用双曲线函数对固结试验中e-p数据进行拟合,得到关于孔隙比与有效固结应力的双曲线模型。在渗透系数与孔隙比关系的基础上,利用e-p双曲线模型推导出软土在压缩过程中固结系数与有效固结应力的关系式,并通过室内渗压试验的数据对该计算模型进行验证。结果表明,该模型较好地反映了固结系数与有效固结应力之间的关系,可以为工程设计提供有益的参考。
The hyperbolic function is used to fit the e-p data in the consolidation experiment to obtain a hyperbolic model of void ratio and effective consolidation stress. Based on the relationship between permeability coefficient and void ratio, the ep hyperbolic model was used to derive the relationship between the consolidation coefficient and the effective consolidation stress of soft soil during compression, and the calculation model was verified by the data of indoor osmotic pressure test . The results show that the model can well reflect the relationship between the consolidation coefficient and the effective consolidation stress, which can provide a useful reference for engineering design.
