Experiment Research on Dynamic Characteristics of Ground Fissure Belt Loess in Xi 'an Area

Article Preview

Abstract:

The Fenwei Basin can be the most developed area of ground fissures as well as the associated geo-hazard in China and even in the world .Considering the ground fissure disasters influence on site condition, especially on the dynamic characteristics and dynamic response of site soil, in this paper, under the condition of constant pressure consolidation, consolidated undrained dynamic triaxial tests are carried on Xi'an area ground fissures belt loess with different confining pressures and dynamical parameters are obtained. Based on the experimental results, the dynamic stress-strain relationship, the change laws of dynamic shear modulus and damping ratio are analyzed. The equivalent visco-elastic constitutive model is also established.
