摘要

摘要: 采用注浆模拟试验及理论分析研究了围岩性质对于注浆压力变化规律及浆液扩散模式的影响。试验采用在注浆模型架内分区充填不同孔隙比土体的方法模拟被注围岩显著的向异性及非均质性；采用多个注浆管依次注浆的方法模拟实际注浆工程中的不同注浆施工阶段。通过开挖揭露浆脉(浆泡)特征研究围岩性质对于浆液扩散形式的影响；通过分析注浆过程中注浆压力数据研究围岩性质对于注浆压力的影响；通过对注浆前后围岩试样进行室内试验测试，获取注浆对于围岩孔隙比及压缩系数的影响规律。研究结果证实：注浆压力变化规律及浆液扩散模式与围岩性质密切相关，通过分析注浆压力变化规律与浆液扩散模式可判定围岩性质，从而为注浆施工过程中的注浆参数动态调整提供依据。相关研究结论在永莲隧道帷幕注浆工程中进行了现场试验，进一步验证了其正确性。

Abstract: The effects of properties of surrounding rock on grouting patterns of slurry diffusion and change laws of grouting pressure are studied by grouting simulation tests. The heterogeneity of practical surrounding rock is simulated by filling the soil with different void ratios into different parts of the model frame. Different stages of practical grouting are simulated by grouting through multiple grouting holes respectively. The diffusion patterns of grouting slurry are obtained by studying the grouting fractures and bulbs of different grouting holes. The change laws of grouting pressure are obtained by analyzing the grouting pressure data of different grouting holes. The effects of grouting on the void ratio and compression coefficient of the surrounding rock are obtained by testing the samples before and after grouting. The results show that the diffusion patterns of grouting slurry and the change laws of grouting pressure are closely related to the properties of the surrounding rock. By analyzing the diffusion patterns of grouting slurry or the change laws of grouting pressure, the properties of surrounding rock can be estimated so as to offer the basis for the improvement of the design of grouting parameters. The conclusions are verified by the curtain grouting project of Yonglian Tunnel.
