摘要
This paper begins with a study of the deformation characteristics and the residual strength of broken rock, which is followed by a research of broken rock after grouting reinforcement. Testing results show that grouting can raise the residual strength of broken rock, and improve the compatibility of lateral and vertical deformations. So the grouting rockmass can keep the steady supporting capacity in a relatively large deformation range. It is helpful for explaining the mechanism of the deformation control in roadway by grouting reinforcement in surrounding rock.
