本文用物理模拟与数学模拟相结合的方法探讨了闭锁区附近的应变场及其演化。研究了不同形状震源体周围震前应变场、位移场的总特点。分析了震前、临震、震时与震后的应变变化。注意了震中附近与外围区的区别。所得结果初步阐明各点的应变过程是与构造条件、破裂过程及该点在应力场中所处位置有关。
In this paper, the physical and mathematical simulation methods combined with the closure of the vicinity of the strain field and its evolution. The general characteristics of the strain field and the displacement field around the epicenter with different shapes are studied. The changes of strain before earthquakes, temporary earthquakes, earthquakes and earthquakes were analyzed. Note the difference between the epicenter and the surrounding area. The results obtained initially clarify that the strain process at each point is related to the tectonic conditions, the rupture process and the location of this point in the stress field.
