Each specimen underwent axial and torsional stiffness testing along with cyclic axial loading to failure.
每个样本均采用循环轴向荷载以至固定失效来测定其轴向刚度和抗扭刚度。

When the resistive moment of surrounding soil is less than the torsional moment 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。
