Study on Poisson Ratio of Soil-Rock Mixture in Low Strain

Abstract:

Longitudinal wave velocity and shear wave velocity of two kinds of the soil-rock mixture samples with different stone content and water content are tested. Then the poisson ratio of the samples in Low Strain can be calculated with the method of wave velocity testing. Analyzing the relationship between poisson ratio, water content and stone content, the dualistic nonlinear models of poisson ratio, water content and stone content are established. The result of verifying is shown that the absolute error of poisson ratio is less than 0.01 and the relative error is less than 2%. The models not only can show the relationship between poisson ratio, water content and stone content but can provide the reference when changing the Rayleigh wave velocity to shear wave velocity each other.
