The cyclic triaxial system is used to investigate the effects of confining pressure, initial shear stress, cyclic stress ratio, and vibration frequency on the dynamic strength characteristics of saturated sand in the Wenchuan area.
Results show that when the vibration frequency is constant, the dynamic strength of sand increases with the increase of the consolidation ratio.
However, when the consolidation ratio exceeds a certain value, the dynamic strength of sand decreases or increases slowly.
The dynamic internal friction angle first increases and then decreases with the increase of consolidation ratio, and the dynamic internal friction angle under different initial shear stresses differs by a maximum of about 12%.
When the failure cycles are constant, the dynamic strength and the dynamic internal friction angle of the sand increase with the increase of vibration frequency, and the dynamic internal friction angle at different frequencies differs by a maximum of about 7%.
When the cyclic stress ratio is constant, the higher the vibration frequency, the greater the cycles required to achieve the failure.
As the cyclic stress ratio decreases, the influence of the vibration frequency on the failure cycles is gradually reduced.
