Energy dissipation and sensitivity analysis of block-hierarchical rock mass on pendulum-type waves propagation
Keywords:
Block hierarchical rock medium, pendulum-type waves, kinetic energy, elastics potential energyAbstract
The study focuses on the energy dissipation of block-hierarchical rock mass and parameters of block-hierarchical structure sensitivity to energy dissipation on the pendulum-type waves propagation in an assembly of block structure which parted alternatively by elastic springs and viscous damping elements. Base on the mechanical model kinetic energy of blocks, elastics potential energy between blocks and mechanical energy of the block mass system are obtained. The effect of block rock structure parameters including block mass, property of visco-elasticity medium between block rocks to the energy dissipation are compared.References
