Experiment study on grouting soil uniaxial compression strength and its acoustic velocity

In order to apply the acoustic velocity to the quality inspection of grouting,the study is performed on the correlation of uniaxial compression strength quality of grouting soil and its acoustic velocities.In this paper,the methods of the grouting soil velocities measurement in the laboratory are introduced briefly,and several key technical problems are also discussed.The studies of the correlation of the acoustic velocity with uniaxial compression strength of grouting soil by regression analysis are detailed.At last,the author give out mathematical models of correlation of uniaxial compreeison strength of grouting soil and its acoustic velocities.
