In order to study the rheological properties of oil shale surrounding rock of tunnel

the triaxial creep experiment of oil shale was carried out with SJ-1B triaxial creepmeter.Based on the experimental results

the nonlinear creep equation of oil shale was established.Taking mine shaft transportation tunnel of Huadian Oil Shale Mine in Jilin Province as an engineering background

this paper analyzes the stress field and displacement field of the surrounding rock of tunnel

and systematically discusses the creep deformation under different support intensities and stress states.The research results show that the creep of oil shale indicates nonlinearity and the fundamental way to control excessive deformation of surrounding rock of tunnel is to change the stress state of rock

appropriately increase the initial prestress of anchor rod and anchor rope.The method presented in this paper provides a theoretical basis for effectively controlling harmful deformation of surrounding rock of tunnel in oil shale mining.
