| 摘 要： | 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。

| Abstract: | The hyperbolic function is used to fit the e-p data of consolidation tests,with which,the hyperbolic model of the void ratio and effective consolidation stress is presented.On the basis of the permeability coefficient and the void ratio,the relationship between consolidation coefficient and effective consolidation stress of soft clay under compression is derived through the e-p hyperbolic model.The results of the indoor experimental of seepage pressure show that the calculation model is reasonable.In this paper,the calculation model reflects well the relationship between consolidation coefficient and effective consolidation stress,which provides a useful reference for the engineering design. |
