在断层发育地区,记录上常见一种强度较大,视速度较正常反射低的波与反射波相干涉。经过分析,说明这种波是反射一反射波.反射一反射波有两种类型:一种是先在地层面反射,后在断层面反射;另一种先在断层面反射,后在地层面反射.文中讨论了两种反射一反射波的运动学特征,并初步讨论了它有较大强度的可能原因,指出了利用这种波可以确定断稜位置.
In the area of fault development, the record of a common intensity, the apparent velocity lower than the normal reflection of the wave and the reflected wave interference. After analysis, it shows that this wave is a reflection-reflected wave, there are two types of reflected-reflected waves: one is reflected first on the formation surface and then reflected on the fault surface; the other is reflected on the fault surface first and then on the ground surface In this paper, the kinematic characteristics of two kinds of reflected-reflected waves are discussed, and the possible reasons for their higher intensity are discussed preliminarily. It is pointed out that the position of the broken edge can be determined by using this wave.
