dc.description.abstractThe paper presents the use of advanced stochastic simulation techniques for estimating the strength behavior of rock materials. The Shore Rebound hardness was measured on fifty rock specimens coming from eleven different geological localities in Czech Republic. The dry unit weight of every tested rock material was determined also. Uniaxial compressive strength of rock was evaluated then by conducting the compression test on every specimen. Empirical distribution of Shore hardness and dry unit weight variables obtained from laboratory tests was approximated by the best fitted theoretical probability distribution. The stochastic simulation using Latin Hypercube Sampling was conducted based on those distributions. Two different equations used for estimating the compressive strength of rock on the basis of Shore hardness in practice was used as model functions. Comparison and statistical evaluation of uniaxial compressive strength of rock determined by compression test and those obtained as a result of stochastic simulation is discussed. The description of probability distribution of uniaxial strength is obtained as a result of introduced analysis, which can be used as input for fully probabilistic design models of rock materials.en
dc.description.abstractPříspěvek se zabývá stanovením pevnosti hornin v prostém tlaku pomocí Shoreho odrazové tvrdosti povrchu. K tomuto účelu byly použity dříve publikované korelační vztahy v kombinaci s pokročilou stochastickou simulací a statistickou analýzou. Rozsáhlé měření Shoreho tvrdosti na různých typech hornin z celého území ČR bylo pro srovnání doplněno o přímé stanovení pevnosti v prostém tlaku.cs
