摘　　要：为了研究裂隙岩体注浆浆液的扩散规律,将单一裂隙简化为椭圆形裂隙,利用广义柱面坐标、牛顿内摩擦定律、达西定律、渗流微分方程和边界条件下的连续性方程,推导出水平椭圆形裂隙中,层流状态下的牛顿液体在渗透注浆过程中各个参数之间的关系,研究了椭圆形岩体裂隙中渗透注浆的扩散规律.In order to study the diffusion law of grouts in fractured rock masses, the shape of single crack was simplified as oval in the model in the paper. Then, according to the generalized cylindrical coordinate, Newton law of inner friction, Darcy law, the seepage differential equations and the continuity equation under the boundary condition, the relationship of parameters in the progress of permeation grouting of Newton liquids in level oval fissure was deduced. Finally, the diffusion law of permeation grouting in oval cracks was studied.
