反射波的一般描述 1.物理地震学的基本概念长期以来,我们一直使用几何地震学的概念来解释地震波。例如以为地震波是以“射线”的形式在介质中传播,入射角等于反射角,又如记录上600米的同相轴对应地下300米的反射段等等。这些概念在解释简单构造地区的地震记录方面是行之有效的,但是到了复杂断块区
General Description of Reflected Waves 1. Basic Concepts of Physical Seismology We have long used the concept of geometric seismology to explain seismic waves. For example, seismic waves are propagated in the medium in the form of “rays” at an angle of incidence equal to the reflection angle. For another example, a recorded reflection phase of 300 meters at a depth of 600 meters and corresponding to the underground phase is recorded. These concepts are effective in interpreting seismic records in simple tectonic settings, but in complex fault blocks
