该理论考虑了水流和电流的相互作用以及地基中孔隙水压力的发展过程,利用等应变等考虑堆载–电渗联合作用的假设建立了轴对称模型的耦合固结方程,并给出了地基中平均孔压和径向固结度的解析解和工程中常用的电极梅花形排布向轴对称排布转化的方法。最后通过参数分析,研究了电源电压和土体的水力渗透系数对平均孔压消散和径向固结度的影响。结果表明:对于堆载–电渗联合作用而言,电源电压越大越好,电渗渗透系数和水力渗透系数比值合适的范围是102～103。
This theory considers the interaction between water flow and electric current and the development of pore water pressure in the foundation. Based on the assumptions of equal load and electro-osmosis interaction, the coupling and consolidation equations of the axisymmetric model are established and the foundation Analytical solution of average pore water pressure and radial consolidation degree and the method of symmetrical arrangement and transformation of the quincunx arrangement of electrodes in engineering. Finally, the influence of the power supply voltage and the hydraulic permeability coefficient of the soil on the dissipation of average pore pressure and the radial consolidation degree were studied by parameter analysis. The results show that for the combined effect of heap-electro-osmosis, the bigger the power supply voltage is, the better the ratio of electroosmosis to hydraulic conductivity is 102 ~ 103.
