基于浆液在孔隙介质中的渗流方程，推导出了圆砾层中浆液流动时间、注浆量、扩散半径的计算式，并在一定的假设条件下，获得了水泥水玻璃浆液粘度随时间变化的规律，探讨了不同注浆压力和浆液流动时间对浆液扩散半径的影响。浆液扩散半径随注浆压力的增大呈非线性增大，随浆液流动时间的增大呈非线性减小。圆砾层防渗注浆工程实例验证了圆砾层双液注浆计算式的正确性。
基于漿液在孔隙介質中的滲流方程，推導齣瞭圓礫層中漿液流動時間、註漿量、擴散半徑的計算式，併在一定的假設條件下，穫得瞭水泥水玻璃漿液粘度隨時間變化的規律，探討瞭不同註漿壓力和漿液流動時間對漿液擴散半徑的影響。漿液擴散半徑隨註漿壓力的增大呈非線性增大，隨漿液流動時間的增大呈非線性減小。圓礫層防滲註漿工程實例驗證瞭圓礫層雙液註漿計算式的正確性。

Based on the seepage equation of the slurry in the porous media,the mathematical formulas of grouting flow time,grout amount,diffusion radius in gravel ground were derived.Under certain condi-tions,the grout viscosity of the cement-silicate grout change with time was obtained,the effects of grou-ting pressure and the time of cement-silicate grout arriving into ground on the grout diffusion radius in gravel ground were analyzed.The results indicate that the grout diffusion radius increase nonlinearly with the increase of the grouting pressure and decrease nonlinearly with the time of cement-silicate grout arri-ving into ground.The calculation results from mathematical formulas accord with the results of grouting engineering,which were grouted of cement-sodium silicate in gravel ground.
