Abstract

Earthquakes can have an extensive effect on the parameters of loess. Therefore, to assess the seismic response and seismic stability of structures in loess fields, the dynamic parameters of loess must be accurately determined. The determination of these dynamic parameters is mainly based on dynamic triaxial tests. Therefore, this paper summarizes the existing experimental results in detail, and the characteristics of the dynamic parameters of loess are analyzed in different fields (e.g., Lanzhou, Xi’an, Taiyuan, etc.). The trends of the dynamic cohesive force, dynamic internal friction angle, dynamic elastic modulus, and dynamic shear modulus under different loess conditions are investigated for different consolidation ratios, different water contents and different vibration times. The results are comparatively analyzed based on the curve-fitting method, and the associated influences on dynamic parameters are summarized. The results indicate that the dynamic cohesive force, dynamic internal friction angle, dynamic elastic modulus and dynamic shear modulus change as the moisture content, vibration time and consolidation ratio vary. This paper provides significant information regarding the regional characteristics of loess and basis for future analyses of the seismic response and seismic stability of structures in loess fields.
