Influence of advanced engineering measures on displacement and stress field of surrounding rock in tunnels

Frontiers of Structural and Civil Engineering doi: 10.1007/s11709-023-0966-x

Abstract: Furthermore, anchor cable and grouting modifications changed the stress field of the rock mass in theThe tensile stress field of the rock mass in the modified anchor cable area was converted into a compressivestress field.The stress field in the modified grouting area changed from shear stress in the fault slip directionto tensile stress in the axial tunnel direction.
