Steady-state response and resonance condition of block rock mass on external periodic excitation

Анотація

Based on the discontinuous and self-stress rock mass in depth the theory of deeprock mass as of a complex hierarchy of block structure is proposed. The block structure of rock mass steady-state response on external periodic excitation is studied. We get resonance equation and resonance condition of the block rock mass structure on external periodic excitation. The effect of local mass and stress state between adjacent rock blocks in block rock mass structure to the steady-state displacement of rock blocks are analyzed.
