The topography was carried out using unmanned aerial vehicles due to its lower cost and time, it was surveyed using a differential GPS obtaining RTK ground control points, allowing to obtain a detailed orthophoto of the study area and obtaining contour lines every 1m. The geological survey was carried out identifying outcrops and structures present in the study area, the lithological environment is characterized by porphyritic andesites, colluvial deposits, saprolites and siltstones. The physical-mechanical parameters were evaluated for the different rock slopes, a lithostructural zoning was carried out in which physical parameters of the massifs were taken with the use of equipment for this purpose such as: compass, low impact sclerometer and Barton comb, in addition a rock sample was taken to determine the physical-mechanical properties of the rock matrix and its resistance to uniaxial compression. The geomechanical classification was carried out for each study station, with the objective of determining the behavior and evaluating in a qualitative and quantitative way the quality of the rock masses by obtaining geomechanical parameters, continuous functions were used for the automation of the calculations, representing through maps the three main classifications such as: RQD, RMR and SMR. Finally, the possible failure mechanisms were identified by means of a kinematic analysis in Dips 6.0 software for each lithostructural zone, taking into account the structural measurements and the results of the tests performed in the laboratory stage. Key words: Slopes, Rock mass, Geomechanical classification, RQD, RMR, SMR. |
