Abstract
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.关键词
