应用三维动态有限元方法研究了中国北部地区的地壳对邻近的渤海与黄海海平面变化的响应。虽然此应力场过于微弱不足以引发地震 ,但发现应力集中的位置及应力场变化较大的位置恰好与某些现代地震的震中一致。这一结果表明研究地壳对广泛分布的载荷的响应对研究区域地震构造是有帮助的
The 3D dynamic finite element method was used to study the response of the crust to the sea level changes in the Bohai Sea and the Yellow Sea in the northern part of China. Although this stress field is too weak to trigger an earthquake, it is found that the location of stress concentration and the location where the stress field changes greatly coincide with the epicenter of some modern earthquakes. This result shows that the study of the response of the crust to widely distributed loads is helpful for the seismic structure in the study area
