Nelson [5] finds that Fig. 2 [4] is remarkably concordant with several published data sets. WebDec 9, 2024 · Some scholars regarded the change in porosity as a deformable characteristic of broken rock mass and established the relationship between the porosity and permeability [24,25,26]. The basic reason for the deformation of broken rock mass is the change in the stress state, but the relationship between permeability and bearing stress changes is ...
