Relationship between Compressive Strength and Primary Wave Velocity of Grouting Soil

摘要

Ultrasonic test technique has been widely used in the inspecting of the quality of grouting. The paper mainly discusses the relationship between compressive strength and primary wave velocity of grouting soil. Four types of grouting soil samples: silt, sand, clay and grit samples, were studied. Ultrasonic test was conducted on primary wave velocity of grouting soil, and compressive test was used to determine compressive strength of grouting soil. Moreover, the data of test had been deducted by the analysis of mathematical statistic. The results suggest that compressive strength and primary wave velocity of grouting soil are correlated and the correlation is exponential function.
