Abstract Bolt-grouting support is active method to combine bolt-spouting and grouting. In light of its support mechanism，a calculating model about its deformation is derived by means of action of bolt represented by volume-force and action of grouting regarded as improvement of properties of rock masses. The action of the support in preserving stability of surrounding rock masses is analyzed and its effect is proved being remarkable with using Kelvin-Voigt model and visco-elastic theory.

Key words： fractured surrounding rock masses bolt-grouting support mechanism deformation of surrounding rock masses visco-elastic analysis
