The analysis of shallow landslides is performed using the infinite slope stability model. This model traditionally uses the Mohr-Coulomb envelope to represent the shear strength of the soil. However, this linear criterion makes that the effective cohesion contributes significantly to the calculated value of the safety factor, which does not occur when you have a shallow soil thickness and, consequently, low effective normal stresses. This work aims to apply a curved strength envelope to the slope stability model and compare it with the classic Mohr-Coulomb failure criterion, spatially calculating the distribution of safety factors for both cases. The methodology consisted of the computational implementation of the two strength approaches in a geographic information system environment being applied to a study area located in the Federal District of Brazil. An initial effort was made to organize the geotechnical and topographic data, as well as the procedure to define the parameters that |
