| Abstract: | The concept and classification of soft rock on the basis of previous studies is introduced.Soft rock can be classified into primary soft rock and secondary soft rock,according to its formation conditions.The present status of research on the permeability of soft rock with fluid-solid coupled theory is described,with discussion of mathematical models,experimental studies and numerical simulations.The theoretical reasons for differences in the permeability of soft rock and hard rock are analyzed,in consideration of the relationship between stress and cracks.Finally,some prospects for future research are presented. |

| Keywords: | soft rock fluid-solid coupling complete stress-strain permeability test numerical simulation |
