通过现场灌浆试验及对灌浆前后古全风化花岗岩的物理力学性质指标测试，结合灌浆作用过程的有限元分析，表明受过上覆岩体自重压力作用后的古全风化岩由于岩体结构发生恢复或再生，物理性质明显优于现代全风化岩；而受一定围压作用的古全风化花岗岩，在一定灌浆压力下，一是使灌浆液较难进入岩石微小孔隙中，再则随灌浆压力逐渐加大，又使相对均质的岩体派生新的拉张裂隙，且将大量浆液吸收。由于上述作用，表现出古全风化花岗岩由灌浆前的结构面不发育，具均质结构变成灌浆后的裂隙（即水泥结石条带）较发育，具非均质结构的特征，且灌浆后岩体的物理力学性质指标有所增长，但提高幅度较小。
Through on-site grouting tests and physical and mechanical properties tests of ancient weathered granites before and after grouting, combined with the finite element analysis of the grouting process, it was shown that the ancient weathered rocks that had been subjected to the overlying rock mass pressure recovered due to the rock mass structure or Regeneration, physical properties are significantly better than modern weathered rocks; and confining pressure of the ancient weathered granite, under a certain grouting pressure, it is difficult for the grout into the small pores of the rock, and then gradually increase with the grouting pressure Large, but also the relatively homogeneous rock derived new tensile fractures, and absorb a lot of slurry. Due to the above-mentioned effects, the paleo-weathered granite shows that the structural plane before grouting is not developed, and the homogenous structure becomes a developed fissure after the grouting (ie, a cement stone strip), which is characterized by an inhomogeneous structure and after grouting. The physical and mechanical properties of the rock mass have increased, but the increase is smaller.
