摘要通过分数布朗函数建立了节理面几何模型，基于N-S方程对裂隙注浆扩散开展有限元分析。考察节理面粗糙度、连通性对浆液扩散的影响，并对修正立方定律的合理性进行分析。当界面层位势较低时，由修正立方定律得到的计算结果偏低，反之计算结果偏高。当界面层接触区域分布较为平均时，其各向异性程度较低，所引起的计算偏差较小，反之计算偏差较大。基于修正的立方定律、界面层本构方程以及浆液流动方程，建立了考虑浆岩耦合效应的注浆扩散公式。考虑浆岩耦合效应后，计算所得到的浆液扩散距离明显提高。并且随着浆液黏度的增加，由浆岩耦合效应所引起的相对计算误差也不断增大。

Abstract：A geometric model of joint surfaces was constructed through the fractional Brown function. The finite element analysis on the basis of N-S equations was conducted to the fracture grouting process. The influence of roughness and connectivity of joint surfaces on the fracture grouting was investigated and the rationality of the modified cubic law was analyzed. When the potential of the interface layer is relatively low，the calculation results of the modified cubic law are lower than the actual values. When the contacting area is uniformly distributed，the degree of anisotropy is low and the calculated deviation is small，and vice versa. A grout spreading formula based on the modified cubic law，constitutive equation of interface layer and grout flow equation was proposed considering the grout-rock coupling effect. The calculated distance of grout spreading is greater than that without the coupling effect. The calculation deviation is also larger with the increase of grout viscosity.

Key words： rock mechanics fractured rock mass grout spreading modified cubic law coupling effect numerical simulation
