Study on the problem of soil consolidation has been always a research hotspot in Geotechnical Engineering, there are many results on the issue so far. In this paper, the electrical components, related operational circuit and the resistance network method which based on Liebmann's principle were introduced to study on the consolidation problem.The resistance network method was used to study on one-dimensional homogeneous soil and layered foundation consolidation problems in this paper. Computation programs, considering the arbitrary distribution of initial pore pressure and the time-dependent loading condition, were developed by using Matlab programming. The reliability of the programs was verified through the comparisons with available analytical solutions. The factors which can be affected the simulation solutions were also analyzed and the quantitative indicators which use for the optimization procedure were proposed. Secondly, the resistance network method and the related program were applied to analyze the one-dimensional consolidation of double-layered soil problems. The consolidation behavior of a three-layer foundation was studied with the thickness, compression modulus and the permeability coefficient of the soil varying.Then, the homogeneous two-dimensional consolidation behavior of soil was analyzed by using resistance network method. The reliability of the programs was further confirmed through comparisons with available theoretical solutions as the analytical solutions being complex and inconvenient to apply. Finally, the electrical components and related operational circuit were applied to the consolidation problem.The circuit and related theory were introduced into the study on the problem of soil consolidation firstly which linked the similarities between the two. It provides a new way to study the consolidation problems of soil. This develops the consolidation theory and makes it more perfect.
