基于深部非连续自应力等级块系岩体构造理论，研究冲击载荷在块系岩体中以摆型波形式传播时岩块间黏弹性性质对摆型波传播的影响。当岩块间具有五种不同黏弹性性质时，通过对块系岩体的始端和末端区域中间岩块加速度响应计算及各岩块加速度正负摆幅幅值分析可知：岩块间黏性变化时，对岩块加速度衰减周期没有影响，但黏性增大时各岩块正负摆幅下降幅度比黏性周期增大时大；岩块间弹性变化时岩块加速度衰减周期均发生变化，但弹性减小时正负摆幅值向平衡位置平移，弹性周期减小时块系岩体的前半部分岩块正负摆幅曲线均出现波动且负摆波动较大，岩块间弹性梯级增大时，岩块加速度迅速衰减，同时各岩块加速度的正负摆幅曲线在初始端区域出现波动。

Based on the theory of discontinuous and self-stress rock mass as block-hierarchy structure in deep, the effect of viscoelasticity in block-rock partings to the propagation of pendulum waves is studied. Acceleration response of intermediate block-rock in the initial and the end regional and amplitude of positive and negative pendulum of each block-rock acceleration on five different kinds of viscoelasticities in partings are analyzed. It is shown that:it has no effect on acceleration attenuation cycle when viscous variation in block-rock partings. However, amplitude of positive and negative pendulum decrease more when viscous partings increases more than periodic increases. Attenuation cycles of acceleration are changed when partings elasticity variation, but amplitude of positive and negative pendulum of each block acceleration translation to equilibrium position when elasticity decreases. In the first half of the block-rock structure, the amplitude of positive and negative pendulum has a fluctuation when elasticity periodic decreases and the negative pendulum fluctuates significantly. Acceleration of each block attenuates rapidly when block-rock partings elasticity step increases;meanwhile, amplitude of positive and negative pendulum have a fluctuation in the initial regional.
