Permeation grouting diffusion radius control method

The invention discloses a permeation grouting diffusion radius control method, which aims at overcoming the defects in the research of permeation grouting slurry diffusion radius influence factors at present, does not carry out the research on the influence of the slurry on the diffusion radius from the property of the slurry, but researches the change of the flow resistance and transverse force of the slurry on the permeability of a porous medium. By taking Bingham fluid as an object, deriving a permeation grouting diffusion radius control equation considering the influence of slurry flow resistance and transverse force on the permeability of the porous medium; the method can reveal the influence mechanism of the slurry on the permeability of the porous medium, and can effectively solve the problem that the traditional theoretical diffusion radius is larger than the actual diffusion radius. 本发明公开了一种渗透注浆扩散半径控制方法，该方法针对目前渗透注浆浆液扩散半径影响因素研究中的不足，不再从浆液本身性质上展开其对扩散半径的影响研究，而是研究浆液流动阻力和横向力对多孔介质渗透率的变化，以宾汉流体为对象，推导出考虑浆液流动阻力
