Block theory methods are popular across the world, and effectively compete with discrete element methods. Their probabilistic extensions are particularly interesting, because they allow the natural, stochastic character of the discontinuity network in a rock mass to be taken into account in models. The article presents the stochastic block stability simulation method (SBSM) developed at the Department of Geomechanics, Civil Engineering and Geotechnics at the AGH UST, along with several other probabilistic, analytical or simulation extensions of classic block theory, namely the Hatzor method, Young's geostatistical models, and Chan and Hoerger's simulations. The paper discusses the properties and range of applications for the said methods. It also presents an outline of the characteristics of classic block theory solutions, that is, the Goodman and Shi method, and the Warburton method.

Metody teorii bloków są na świecie popularne i z powodzeniem konkurują z metodami elementów dyskretnych. Jednak szczególnie ciekawe są ich probabilistyczne, symulacyjne rozszerzenia, pozwalające na uwzględnienie w modelach naturalnego, stochastycznego charakteru sieci nieciągłości w masywie skalnym. W artykule przedstawiono metodę stochastycznej symulacji stateczności bloków (ang. SBSM) opracowaną w Katedrze Geomechaniki, Budownictwa i Geotechniki AGH oraz niektóre inne probabilistyczne, zarówno analityczne jak i symulacyjne rozwinięcia klasycznych rozwiązań teorii bloków: metodę Hatzora, geostatystyczne modele Younga, symulacje Chana i Hoergera. Przedyskutowano właściwości i zakres zastosowań wymienionych metod. Krótko przedstawiono też cechy klasycznych rozwiązań teorii bloków: metody Goodmana i Shi oraz metody Warburtona.
