Abstract

Abstract: A set of constant volume cyclic simple shear tests was performed to study the impacts of various cyclic stress ratio (CSR = 0.21~0.53) and overconsolidation ratio (OCR = 1~4) on the dynamic shear characteristics of granite residual soil. This study analyzed the stress-strain relationship, degradation index, dynamic elastic modulus, and cumulative shear strain of residual soil. The results showed that the granite residual soil exhibited softening behavior at different overconsolidation ratios. The softening index decreased with an increasing number of cycles, showing a linear relationship at low stress levels and a nonlinear relationship near the critical cyclic stress ratio. The dynamic elastic modulus exhibited significant attenuation with an increase in OCR. The threshold for the cyclic stress ratio increases with higher overconsolidation ratios under cyclic loading. In addition, a prediction model for the cumulative shear strain was developed considering the overconsolidation ratio, cyclic stress ratio, and number of cycles. This research provides valuable insights for analyzing the cumulative deformation of granite residual soil subgrades under traffic loads.

Key words: granite residual soil, overconsolidation ratio, cyclic stress ratio, cumulative shear deformation
