摘要
在破裂岩石残余强度和变形性能研究的基础上，进一步开展其注浆固结体的力学性能试验研究。试验证实注浆固结后破裂岩块残余强度有不同程度的提高，同时发现其侧向变形和径向变形趋向协调，从而提高了破裂岩块的塑性变形性能，并在较大变形范围内保持稳定的承载能力。试验结果有助于解释围岩注浆加固控制巷道变形的机理。
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.
