espanolEsta investigacion, consiste en la determinacion del parametro mecanico de resistencia a compresion Uniaxial en la roca y su correlacion con la humedad y porosidad eficaz, propiedades fisicas de la roca. Por su objetivo de estudio, el proyecto se engloba dentro del marco de la mecanica de rocas. Las rocas seleccionadas para la investigacion fueron tomadas de una cantera del Sur Occidente Colombiano. La investigacion condujo, a la determinacion de ecuaciones que permiten estimar la resistencia a compresion Uniaxial de la roca a partir de su porosidad eficaz y del contenido de humedad. Es importante resaltar que este tipo de correlaciones son representativas para rocas que gocen de caracteristicas litologicas similares a las utilizadas en la experimentacion. Finalmente se presentan los resultados con sus analisis y conclusiones de la investigacion. EnglishThis research consists of the determination of the mechanical parameter of resistance to uniaxial compression in the rock and its correlation with moisture and effective porosity, physical properties of the rock. By its goal of study, the project comes within the framework of the mechanics of rocks. Rocks selected for research were taken from a quarry in South West Colombia. The investigation led to the determination of equations that allow to estimate the resistance to uniaxial compression of rock from its effective porosity and moisture content. It is important to highlight that such correlations are representative for rocks benefiting from lithological characteristics similar to those used in the experimentation. Finally the results are presented with their analysis and conclusions of the research.
