Resumen
En a la actualidad no existe ningún método analítico que tenga en cuenta el efecto de la rugosidad en el cálculo de la capacidad de carga, ésta investigación partirá de esta condición y cuantificara el efecto que provoca en las cimentaciones superficiales empleando un modelo computacional que se realizará mediante el Abaqus 6.14 que está basado en el Método de Elementos Finitos (MEF).Su calibración será a partir de métodos analíticos porque no se encontraban métodos experimentales ,asumiendo que está más que probada su veracidad en la capacidad de carga.
Una vez construido el modelo computacional los resultados obtenidos se compararan con los resultados analíticos que estarán basados en Hojas de Cálculos de Matchad para ellos se utilizaran varios suelos con distintas propiedades físico-mecánica donde se podrá determinar el efecto de la rugosidad en cada uno de ellos. Estos resultados permiten considerar la posibilidad de introducir un coeficiente en la expresión de capacidad de carga.
At present there is no analytical method that takes into account the effect of roughness in the calculation of the load capacity, this research will start from this condition and quantify the effect it causes on the surface foundations using a computational model to be carried out by means of the Abaqus 6.14 that is based on the Finite Element Method (FEM). Its calibration will be based on analytical methods because experimental methods were not found, assuming that it is more than prove its veracity in the load capacity. Once the computational model has been built, the results obtained will be compared with the analytical results that will be based on Matchad's Mathematical Calculation Sheets. For them, several soils with different physicomechanical properties will be used where the effect of the roughness in each of them can be determined. These results allow to consider the possibility of introducing a coefficient in the expression of load capacity.
