RHEOLOGICAL STUDY ON BOLT-GROUTING SUPPORTED ROADWAYS IN SOFT ROCK
锚注软岩巷道流变研究

The computing models of bolt-grouting support for two-way unequal roadways in soft rocks are set up. Rock strata around roadway are divided into reinforced zone of bolt-grouting support and unreinforced zone,in which different viscoelastic models are used and the stress-displacement relationship of roadways is derived. The viscoelastic solution is reasonable compared with practical observed displacement curve of bolt-grouting supported roadways in soft rocks.
