基于广义达西定律和球形扩散模型理论，推导了均匀砂层中指数型流体在注浆过程中有效扩散半径的计算公式。结果表明，注浆压差与浆液流变参数c、n及扩散半径有关，注浆压差随c呈线性规律变化，随n呈非线性规律变化，浆液压差随半径增大而增大，且增大程度受浆液流变参数的影响显著。
Based on the generalized Darcy’s Law and theory for spherical diffusion model,a formula for calculating the effective diffusion radius of exponential fluids injected into homogeneous sandy stratum in grouting is deduced.It shows that the grouting pressure difference is related to the grout rheology parameters c,n and the diffusion radius.The grouting pressure difference change with c by linearity rule and with n by nonlinearity rule.Grouting pressure difference increases with increasing radius,and the increasing grades are notably affected by the grout rheological parameters.
