Simulación numérica del modelo de consolidación no lineal de Davis y Raymond

Abstract

[SPA] La ecuación de gobierno que define el proceso de consolidación en suelos saturados viene regida por el coeficiente de consolidación cv, de manera que, a valores mayores del mismo, el proceso de consolidación por disipación del exceso de presiones intersticiales es más rápido. El modelo de consolidación no lineal de Davis y Raymond asume que el valor de este coeficiente permanece constante durante todo el proceso, pero no así las propiedades del suelo de las cuales depende su valor. Empleando el método de redes, se ha resuelto numéricamente este modelo, obteniéndose soluciones muy precisas, con tiempos de computación mínimos. [ENG] The governing equation that defines the consolidation process in saturated soils is governed by the coefficient of consolidation cv, so that, for higher values of this, the consolidation process by dissipation of the excess pore pressure is faster. The nonlinear model of consolidation by Davis and Raymond considers that the value of this coefficient remains constant throughout the whole process, but not the soil properties of which depends on its value. Using the network method, the model has been solved numerically, obtaining very accurate solutions, with very low computing times.
