Uso de la clasificación geomecánica utilizando el método RMR para la estimación preliminar de los requerimientos de sostenimiento de los taludes en el cerro La Potra del Proyecto Hidroeléctrico Bajo Frío, República de Panamá.

Abstract

In this project we applied geomechanics classification detail Rock Mass Rating (RMR) to estimate preliminary injunction sustaining the rock slopes of Cerro La Potra. Furthermore, it provides for a viable solution stability through shotcrete. The project aims is to determine the quality of the rock mass and strength parameters estimated for the support of the slopes of Cerro La Potra. Within the methodology is first necessary to consider all variables RMR method, which are essentially the compressive strength of the rock, the index RQD (Rock Quality Designation), spacing of discontinuities, discontinuities status the presence of water in the rock mass and finally the orientation of the discontinuities. All these parameters are determined in situ research. Generally the RMR geomechanics classification reported two conditions predominated medium quality and quality. The latter was presented at the bottom of the hill, which is normal since weathering is greater in the upper slopes. The fiber-reinforced shotcrete with a thickness of 5 cm is the optimal solution for rock slopes of Cerro La Potra margin right from the point of view of RMR geomechanics classification
