在对断裂分带研究的基础上，尝试对缓倾角断裂（指倾角小于45”的断层）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．通过系统的定量研究，指出除断层各带自身材料力学性质（如波阻抗等政十 Based on the study of the zonation of faults, an equivalent simplified geologic model is attempted to establish for the gentle dip fracture (fault with dip less than 45 "). According to the different attenuation mechanism of each belt, different mechanical models and numerical calculation methods , The dynamic response of the stress wave through the fault structure is analyzed.According to the quantitative research of the system, it is pointed out that besides the mechanical properties of each material of the fault zone (such as wave impedance,
