When the resistive moment of surrounding soil is less than the torsionalmoment of eccentric jacking force, stability failure of pipeline occurs and pipes deviates from the designed axes.
管道失稳是由于管道周围土体提供的抵抗力矩小于偏心顶推力而产生的扭转力矩,造成管节偏离设计轴线。

The torsionalmoment of transmission shaft and power of electric motor are reduced by the method.
此方法可降低传动轴上所受的扭矩,减少了电动机的功率。
