An extended super/subloading surface model for soft rock considering structure degradation [PDF]
PLoS ONE, 2021 The strain-softening and dilatancy behavior of soft rock is affected by the loading history and the development of structure. This study regards soft rock as a structured and overconsolidated soil and develops a new elastoplastic model based on the ...

Failure mechanism and supporting measures for large deformation of Tertiary deep soft rock
International Journal of Mining Science and Technology, 2015 The Shenbei mining area in China contains typical soft rock from the Tertiary Period. As mining depths increase, deep soft rock roadways are damaged by large deformations and constantly need to be repaired to meet safety requirements, which is a great ...
