Laboratory-Scale Modeling of Trigger Effects due to Gas Filtration in Fault Zones in Rocks

Resumo

The process of a rigid rough plate shear in a granular medium is considered. The influence of three factors is analyzed: stiffness of loading, weak shocks and air filtration. It is shown that weak shock actions and air filtration, either separately or jointly, can act as a trigger of uncontrolled dynamic release of elastic energy in rock mass.
