摘要
本文是在断层的教学模型基础上,提取地震波的运动学和动力学传征参数,研究它们在断点上的变化规律及与纵向分辨率的关系,为应用多元地震参数模式识别方法进行小断层识别提供了一定的理论依据。研究结果表明:(1)在信噪比高的地区,可查明5m左右的断层;(2)进行断层模式识别时。
Based on the mathematical model of faults.this paper takes the kinematic and dynamic character-istic parameters of seismic wave to study the variation law of these parameters on the fault points and their relations to the longitudinal resolution. It provides a certain theoretical basis for conducting small faults discrimination using the method of plural seismic parameter mode. The result of study shows that: (1) in areas of high signal -noise ratio.the faults about 5m can be detected; (2) when conducting the discrimination of fault mode, the effective seismic characteristic parameters should be used.
