Deformation control criterion of shield tunnel under lateral relaxation of soft soil

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 5,   Pages 780-795 doi: 10.1007/s11709-023-0944-3

Abstract: However, deformation control standards for such situations have not been clearly defined.Subsequently, a deformation control criterion is established.Based on the mechanical pattern of the segment structure and the acoustic emission, the deformation responseof a segment can be classified into three stages: elastic and quasi-elastic, damage, and rapid deformationHowever, the segment deformation must be controlled when the ellipticity is 2.71% to 3.12%; in this regard
