Numerical Analysis on Effect of Rock Rheology on Fully-Grounded MFRP Bolt Stress

Abstract:

Article Preview

As to the time effect of prestress in bolt in geotechnical engineering, the stress distribution in fully-grounded MFRP bolt and its trend influenced by rock rheology is obtained by FEM. The Burgers body which is able to model the primary and secondary creep regions of the rock mass is applied to analyze the time effect of prestress in MFRP bolt. The results show that rock rheology has a great effect on MFRP bolt stress.
