本文利用我国在日本秋田地震时有水位阶变的65口井孔的观测资料,计算了地震时引起我国应力场的调整变化,应力变化量值从8.7—6.4×10~4Pa。并分析了我国应力场调整时,应力增加区和应力降低区交替出现的可能原因。
In this paper, we use the observed data of 65 boreholes that have water level changes during the Akita earthquake in Japan to calculate the change of stress field caused by the earthquake in China. The value of stress change is from 8.7 to 6.4 × 10 -4 Pa. The possible reasons for the alternation of stress increase zone and stress reduction zone are also analyzed when the stress field of China is adjusted.
