ROMAN, Daniel  e  CHIO, Gustavo. Analysis of sliding block models for prediction of the dynamic behavior of the mass removal phenomenon: One-parameter Model and Two-parameter Model. bol.geol. [online]. 2018, vol.40, n.2, pp.113-124. ISSN 0120-0283.  https://doi.org/10.18273/revbol.v40n2-2018007.

This study aims to show the variations, from a conceptual perspective, between two sliding block models. The evaluation of these two models allows to determine the kinematic variables (range, velocity and acceleration) of a sliding mass. Herein, is assessed how the outcomes of these models are affected by varying the parameters of the friction angle (φ), turbulence (ξ), and pore pressure coefficient (ru). To achieve this, the equations of motion are solved through analytical and numerical techniques assuming that, for an isotropic material, the motion is one dimensional and function of the independent variables. Finally, a comparison between the velocities obtained with each model is presented, and a concluding remarks section in which the practical use of each solution in the avalanche dynamics problem is argued.

Palavras-chave : Landslide; turbulence parameter; friction; power line; pore pressure coefficient.
