For electro-osmotic consolidation in unsaturated soils, coupled deformation, inconsistent changes in hydraulic conductivity and electro-osmotic permeability with matric suction, and a decrease in effective voltage with time occur simultaneously. To consider all of these processes, an analytical solution was proposed. The time-stepping method was adopted in the calculation of the solution to depict the nonlinear change in shrinkage deformation with matric suction. The accuracy of the proposed analytical solution was validated by comparison with results from laboratory tests and from a previously presented solution without considering coupled deformation. Then, a parametric study was conducted. The results indicate that the dissipation of the pore water pressure is slow when considering coupled deformation, but a large volume of water is discharged in the end, especially for soils with a large volumetric shrinkage index C_m. A larger final negative pore water pressure and discharged water can be predicted by considering the inconsistent changes in hydraulic conductivity and electro-osmotic permeability. Finally, with the consideration of the decrease in effective voltage over time, both the maximum negative pore water pressure and final drainage decrease, which is consistent with field observations.

对于非饱和土壤中的电渗固结，会同时发生耦合变形，基质吸力引起的水力传导率和电渗渗透率的不一致变化以及有效电压随时间的下降。为了考虑所有这些过程，提出了一种分析解决方案。解的计算采用时间步长法，以描述基质吸力引起的收缩变形的非线性变化。通过与实验室测试结果和先前提出的解决方案进行比较，而不考虑耦合变形，验证了所提出分析解决方案的准确性。然后，进行了参数研究。结果表明，考虑耦合变形时，孔隙水压力的耗散较慢，Ç_米。通过考虑水力传导率和电渗渗透率的不一致变化，可以预测更大的最终负孔隙水压力和排放水。最后，考虑到有效电压随时间降低，最大负孔隙水压力和最终排水都降低，这与现场观察一致。
