While direction of previous main faults that intersect the maximum principal stress 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。

Keeping the minorprincipal stress and medium principal stress fixed, the loading in the direction of the major principal stress is a potential stress path in practical projects.
保持小主应力、中主应力不变，在大主应力方向加荷是实际工程中可能存在的一种应力路径。
