Abstract

To explore the characteristics of shear wave velocity of saturated red clay, triaxial saturated specimens with different dry densities were prepared. The modified triaxial bender element system was used to conduct consolidated undrained (CU) triaxial tests on the red clay. The variation law of the shear wave velocity of the red clay specimens was analyzed. Eventually, an evaluation model for the shear wave velocity of saturated red clay was established. The results indicate that: (1) The shear wave velocity of saturated red clay increases with the increase of confining pressure, dry density, and effective stress, while it decreases with the increase of void ratio. The relationship between shear wave velocity and confining pressure as well as effective stress follows a power function. (2) Four different fitting methods(linear, quadratic polynomial, power function and exponential function) are adopted to analyze the correlation between the shear modulus and effective stress of saturated red clay with different dry densities. The fitting accuracy is in the order of power function fitting > exponential fitting > binomial fitting > linear fitting, thus obtaining the quantitative relationship between the shear modulus and effective stress. (3) Based on the correlation between the shear wave velocity and shear modulus of soil, with specific gravity, void ratio and effective stress as variables, a shear wave velocity model for saturated red clay is established. Upon inspection, the measured values of this model are in good agreement with the calculated values, and it can provide an evaluation index for the evaluation of the effective stress of saturated red clay. This model can effectively reflect the change in the stress state of saturated red clay under consolidated undrained conditions through shear wave velocity, and provides a reference index for in-depth research on the monitoring and early warning of red clay landslides.

Key words： geotechnical engineering; shear wave velocity; triaxial test; saturated red clay; effective stress
