Análisis geotécnico de estabilidad en taludes en la zona de presión de la central San Francisco del proyecto hidroeléctrico Las Rocas, entre los años 2019 2021

Abstract

Abstract:The geotechnical analysis of the slopes of the pressure zone of the San Francisco exploitation of the Las Rocas Hydroelectric Project, is based on the available information that mainly includes geotechnical monitoring data, in such a way to validate or establish new design parameters, to calculate the stability of the slopes under current conditions. For the analysis, the various materials that make up the slope are considered, such as soils, or the existence of low-resistance or high-resistance rocks with the physical properties of each one. The rocks can be crossed by fractures, faults, laminations and folds that would produce instability. Therefore, the present work was developed with the objective of evaluating the stability and determining the critical areas that are threatening the main works of the San Francisco Hydroelectric Plant, obtaining the geological and geotechnical model of the study area, where the results were incorporated. of field and laboratory investigations, in addition to the integration of the results of the monitoring of superficial and deep displacements, then it was correlated with the rains in the area and the safety factors that indicate the risk when the land displacements occur were finally determined.
