Tavallisimpien suomalaisten kivilajien kalliomekaaniset ominaisuudet yksiaksiaalisten puristusmurtolujuus- ja vetomurtolujuuskokeiden perusteella

摘要

This Master’s thesis analyzes the results of two basic rock mechanics laboratory tests: Uniaxial compressive strength test and Brazil tensile strength test. This study also explores the known factors affecting the measurements in the uniaxial compression test and Brazil test results. Since statistics and correlations play a significant role in research, a big part of this Master’s thesis is built around the descriptive statistics and regression analysis. Consequently, in this Master’s thesis the tests results for different rocks are described in detail and rely quite sufficiently on the statistical and regressional analysis.In its main part, this thesis anylizes the linear relationship between the obtained results for mechanical parameters of the Finnish rocks obtained by condicting the uniaxial compressive and Brazil tensile strength tests. The conclusions regarding the compressive and tensil strengths values for the most usual Finnish rocks are made using statistical analysis. After that, the results obtained in this Master’s thesis are compared against the results available from similar publications.The analysis of results confirms that the strength and mechanical properties of the Finnish rocks differ quite a lot depending on the place of occurrence. Based on the statistical analysis made in this thesis, have been lead out several multiple regression models for determination uniaxial compressive strength.
