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。 Based on the research on the zonation of faults, an equivalent simplified geologic model is proposed for the gently-inclined faults with dip less than 45 °. According to the different attenuation mechanisms of different zones, different mechanical models and numerical methods are used respectively to analyze the stress Through the systematic quantitative study of the dynamic response of the wave through the fault structure, it is pointed out that the dip of the fault, the thickness of each zone, the presence of fault mud and the structure of the lens zone with the exception of the mechanical properties of the fault zone (such as wave impedance) Size, topology and so on are important factors affecting the stress wave propagation.
