Generación de un algoritmo de simulación para la susceptibilidad de suelos a la remoción en masa utilizando el software MATLAB

Abstract

In the present document was realized a simulation algorithm using the software MATLAB. The application implemented different types of equations from the infinite slope method in order to determinate a factor of safety in a slope. To achieve this objective were used different types of equations, each one correspond to the infinite slope model and that equations are: for a dry soil and without cohesion, with pseudo-static seismic coefficient, and others. The parameters needed to use all the equations are the slope angle, internal friction angle, thickness of the soil layer, thickness of the wet soil layer, cohesion, saturated soil unit weight, wet soil unit weight, pore pressure, phreatic level depth, effective unit weight, slope depth, horizontal seismic coefficient, vertical seismic coefficient, stability forces, total weight of the slope, resistance to shear stress, thickness of the soil layer, thickness of the saturated soil layer, resistance generated by trees, overload by the tree, which will serve of input data of the algorithm. Finally was created an algorithm with a friendly graphic interface to be used by any user, in which the required input data to execute the program is clearly visible. After be used, the results are saved on the application any times as the user ask for (with a maximum of 10 times in only one session). In order to test the algorithm, it was taken some soil samples on Santo Tomas University Campus Loma Linda´s ground and a slope near from Pipiral’s Toll on the Bogotá- Villavicencio road. The safety factor calculated by the software for Loma Linda is 1,164 and Pipiral 0,913 which indicates that are zones with medium and high landslide risk.
