Research on Deformation Control Measures of Surrounding Rock in Soft Rock Tunnel
IOP Conference Series: Earth and Environmental Science, 2021 Abstract In order to study the control measures of soft rock tunnel surrounding rock deformation, based on the restraint effect of shotcrete anchor support on it, a support model was constructed, and numerical simulation was used to compare and analyze the restraint effects of different bolts controlling the surrounding rock deformation.

Gas inclusions and their expansion power as foundation of rock “locked in” stress hypothesis [PDF]
, 2014 About 35 years ago, Professor TAN Tjong-Kie proposed the hypothesis of rock “locked in” stresses and considered the “locked in” stresses were the failure cause of rock engineering projects.
