The measured maximum horizontal principalstress orientation in North China by different methods were compared in this paper.
本文分析、比较了由不同方法测得的华北地区最大水平主应力方向。

While direction of previous main faults that intersect the maximumprincipalstress by minor Angle also probably becomes the major migration direction of oil and gas.
与最大主应力小角度相交的先期主要断裂的方向也可能成为油气运移的主要方向。

The results show that the larger the acute Angle between valley trend and regional maximumprincipalstress is, the more intensive its influence on rock stress in valley is.
