为了研究阴极抽真空联合电渗法的一维固结模型,在Esrig电渗固结方程的基础上,考虑阴极抽真空的边界条件,建立了阴极抽真空联合电渗法的一维固结模型,用分离变量法进行了求解,得到了阴极抽真空联合电渗过程中土体内部超孔压的解析解公式,并进行了讨论。结果表明阴极抽气的电渗法具有真空预压及电渗的优点,能使土体中产生的超静孔隙水压力更加均匀,从而使加固效果更加均匀。
In order to study the one-dimensional consolidation model of cathodic vacuum infusion combined with electroosmotic method, based on the Esrig electro-solidification equation, considering the boundary conditions of cathodic vacuum extraction, a one-dimensional consolidation model , And solved by the method of separate variables. The analytical solution of the excess pore pressure inside the soil during cathodic vacuum combined with electro-osmosis was obtained and discussed. The results show that the cathode pumping electroosmosis method has the advantages of vacuum preloading and electroosmosis, which can make the excess pore water pressure in the soil more uniform, so that the reinforcement effect is more uniform.
