Description
  • In this paper an inverse analysis which makes possible to identify some parts of horizontal stress tensor is described. As the parameters applied for the inverse analysis are exploited the displacement on the concrete lining of a shaft.The displacements are created by excavating the rock in the process of the construction of the shaft. The directions of principal stresses and their ratio can be established from the inverse analysis. The anisotropy of horizontal stresses influences the instability of such underground constructions. The method was applied for the detection of the characteristics described above for the Frenštát coal mine in the Beskydy Mountains. The structure of anisotropy can be applied for the optimal installation of bolt reinforcement, which is discussed in this paper as well.

  • Zpětná analýza umožňuje určit některé složky tenzoru napětí, což je popsáno v tomto článku. Jako parametry vstupující do inverzní analýzy jsou použity deformace betonového ostění těžní jámy. Inverzní analýza umožňuje určit směry hlavních napětí a jejich poměr. Anizotropie původních napětí ovlivňuje stabilitu podzemních konstrukcí. Metoda byla použita k určení těchto charakteristik na dole Frenštát v Beskydech. Znalost struktury anizotropie umožňuje optimální instalaci kotevní výztuže, což je rovněž diskutováno v článku. (cs)
