Caracterización geomecánica del macizo rocoso, para su aplicación en geotécnia, en el sector Lucarqui, Loja-Ecuador.

Abstract

The present investigation is carried out in order to obtain the physical mechanical parameters for the geomechanical characterization of the rock mass in a section of 1.33 km road in the Lucarqui sector, using specialized field equipment for this purpose such as: Barton comb, low impact sclerometer and compass; as well as laboratory tests: simple compression, density, sclerometry in nuclei and Tilt Test. As a result of this work we have obtained a series of physical-mechanical parameters that allow us to determine the behavior and quality of the rock mass using 5 main classifications: RQD, RMR, SMR, Q BARTON and GSI, as well as the most suitable characterization method for the study area. With the data obtained from the characterization the mass breakage parameters are determined applying the Hoek-Brown method. The results obtained during the investigation determine that the quality of the rock mass is of type II (Good) and type III (Regular), whose evaluation determines that the mechanical behavior of the rock mass in the study area is stable or partially stable
