本文根据二维模型实验的结果,探讨了地震波辐射图型、震源机制解以及构造应力方向之间的关系.地震波辐射图型取决于地震时震源介质运动的方式.它不但与震前存在的应力有关,而且依赖于震源区的地质条件等因素.根据岩石力学实验和我们实验的结果,可以认为,构造应力的主压应力方向要比震源机制解推断的释放主压应力方向更偏近断层面一些.
Based on the results of two-dimensional model experiments, this paper discusses the relationship between the radiation pattern of seismic wave, focal mechanism solution and tectonic stress direction.The radiation pattern of seismic wave depends on the mode of motion of seismic source medium during earthquake.It not only relates to the existing stress And depend on the geological conditions in the source area.According to the results of rock mechanics experiments and our experiments, it can be considered that the direction of the principal compressive stress of tectonic stress is closer to the fault plane than the principal compressive stress direction deduced by focal mechanism solution some.
