| 摘 要： | 根据断裂条件和充填质条件，基于理性力学观点，研究断层面对地震子波的反射和透射问题。先将断层面用弹塑性接触面模型加以力学描述，应用增量波动概念引出地震波的边界条件，然后得到断层面的理论反射系数和透射系数。结果表明，断层面反射依赖于充填质的力学属性；并且在流体充填时，断层面对透射波表现为带通滤波特性。据此可以用于检测断层含水性。

| Abstract: | According to geological fault condition, based on the viewpoint of rational mechanics, this paper researches the problem of seismic reflection induced by geological faults. The results show that: seismic reflection from fault relates to the mechanical features of material filled in fault; and when the filling material is fluid the fault behaves as a band-pass filter. It may have theoretic meaning to study the reservoir feature controlled by faults with the help of seismic data. |
