Investigation of Stress Relaxation Characteristics of Fine-Grained Soils Based on CPT and Viscoelastic Constitutive Modeling
Stress relaxation is a common phenomenon in fine-grained soils. However, most existing studies rely on laboratory triaxial tests, with limited attention to in situ methods. In particular, the relaxation behavior under cone penetration test (CPT) conditions has not been systematically investigated. Through triaxial re...
