摘要
在对断裂分带研究的基础上，尝试对倾角小于４５°的缓倾角断裂建立起等效简化地质模型，针对各带的不同衰减机理，分别采用不同的力学模型和数值计算方法，分析了应力波通过断裂构造的动力响应，通过系统地定量研究，指出除断层带自身材料力学性质（如波阻抗等）外，断层的倾角、各带的厚度、断层泥带的存在及构造透镜体带颗粒大小、拓扑结构等是影响应力波传播的重要因素。
The form of the slow angle of the faults which affects the shock wave propagation greatly is suggested. The geological models of the faults with slow angle and the associated characteristics of the different geologic belts are established. The material models of the faults, the dynamic equation and the numerical method for solving the equation are developed. The attenuation law for the variation of the parameters is analyzed according to the calculated results. The wave propagating in the faults is influenced by the impedance of the wave, the width of the faults surface, the particle size and its topo structures.
