Original Title

English Title

Determination of Rock Parameters Used for Calibration of Constitutive Model

Type

Peer-reviewed article not indexed in WoS or Scopus

Original Abstract

Mathematical modeling is an important part of designing underground and other structures. However, the accuracy of the obtained results is strongly dependent on the input parameters quality of the selected material (constitutive) model. An insight into this issue is outlined in this article. Special emphasis was placed on various possibilities of laboratory determination of the necessary parameters for calibration of the Mohr-Coulomb and Hoek-Brown constitutive models. Described procedure was also applied to a selected rock type – Čeřínek-type granite of the Moldanubian pluton, a candidate rock in which a deep geological repository for used nuclear fuel and high-level radioactive nuclear waste might be built in a future.
