ABSTRACT: The network method is revealed as a useful numerical technique to solve non-linear problems such as the soil consolidation process, ruled by diffusive equations in which the coefficients of the addends are complex functions of the dependent variable, the effective pressure. The equivalence between the physical and network model is established by introducing a formal analogy between the dependent and independent variables of the problem and the different elements or variables of an electric circuit. Based on the network method, and making use of the powerful computational algorithms implemented in the circuit simulation codes, the numerical models proposed in this paper are solved, performing an analysis on the accuracy of the method, computing times and grid size required depending on the degree of non-linearity of the problem. Finally, from a series of illustrated applications, a comparison is made between the different models proposed, analyzing in depth the most general and precise of them.
