چکیده

The 3D point clouds obtained from the low-cost, remote, and precise SfM (Structure Motion) technique allow extraction acquisition of discontinuities their characteristics both manually, with compass virtual ruler Cloud Compare software, automatically DSE (Discontinuity Set Extractor) program, which is faster, more accurate, safe. Some control plans have been used, basically consist identifying one or several fractures taking measurements on them manually remotely. difference between types around 5°, we believe reasonable since it within precision repeatability a geologist’s compass. This work analyzes stability six slopes (five excavated natural) by applying five different analysis methodologies based rock mass classification system (SMR, RHRSmod, Qslope), kinematic analysis, analytical (limit equilibrium). Their results were compared what was observed in field to identify most appropriate adjusted reality. necessary parameters for analyzing each slopes, such as orientation, quantity, spacing, persistence discontinuities, automatic analysis. type eliminates subjectivity authors, although findings are related resemble those manually. main contribution article consists application fast low-cost techniques evaluation slopes. It that high demand today many Andean countries, this aims provide an answer. These suggested scientific articles will later be integrated into some procedures taken account technical reports. show available information techniques, SMR methodology presents best adjusts better reality study area. Therefore, parameter determine rockfall hazards through modified RHRS.

Slope stability analysis with FLAC and limit equilibrium methods

The factor of safety for slopes (FS) has been traditionally evaluated using two-dimensional limit equilibrium methods (LEM). However the FS of a slope can also be computed with FLAC by reducing the soil shear strength in stages until the slope fails. This method is called the shear strength reduction technique (SSR). Many authors have pointed out several advantages of SSR over the limit equilib...
