This paper also determined the predominant direction of the fault belt based on the aftershock distributions of the moderate, strong earthquakes and on the long axis of the isoseismic zone, and discussed the characteristics of current tectonic movement in the north segment.
此外根据中强地震的余震区分布和宏观极震区长轴确定了该带发震断层的优势方向，由此讨论了南北地震带北段现今构造运动的特点。
The result shows that when the direction of roadway axis is parallel to that of the greatest principal stress, the effect of tectonic stress on the stability of the roadway is the smallest.
