中文摘要：

深部岩体工程存在一种特殊的岩体动力现象即摆型波传播现象,摆型波在岩体中低频低速传播并伴随着较大的岩体能量传递。针对摆型波传播过程块系岩体的能量传递规律,基于深部岩体的非连续自平衡应力等级块系构造理论,研究摆型波传播过程块系岩体中岩块与其周围软弱介质之间的能量转化规律,分析自应力块系岩体中的能量传递规律。经分析得到：摆型波传播过程块系岩体的能量转化表现为岩块的动能和其周围软弱介质的势能之间存在相互转化,动能和势能在相互转化过程中不断向前传递,给出块系岩体能量传递与转化的表达式,并通过计算分析得到块系岩体局部区域能量变化呈现周期递减规律以及整个块系岩体的动能和势能变化符合指数耗散规律。

英文摘要：

The pendulum-type wave is a special rock mass dynamic phenomenon in deep rock mass engineering. It is the propagation with low frequency and low speed in rock mass, which carries the obvious energy propagation. According to the energy transfer rules in the propagation process of pendulum-type waves in block-rock mass, the laws of the energy transformation between rock block and nearby weak medium is studied based on the block-hierarchical theory of deep rock mass which is composed of discontinuous and self-balance stress block-rock. The laws of energy transfer in block-rock mass with self-balance stress are investigated through analysis. The energy conversion in the block-rock mass is the mutual transformation between the kinetic energy of the rock block and the elastic potential energy of the nearby weak medium during propagation of pendulum-type waves. The kinetic energy and elastic potential energy transfer forward on during mutual transformation of energy. The expression for energy transfer and transformation in block-rock mass is given. Through calculation and analysis, the laws of energy variation in local area exhibits cyclic attenuation, and the variation and dissipation of kinetic energy and elastic potential energy have exponential relationship in the whole block-rock mass.
