Abstract

Abstract: The clay collected from an engineering site is studied with GDS cyclic triaxial test to analyze the characteristics of dynamic modulus and damping ratio. It is shown that the 1/E_d-ε_d curve can be described by the approximate linear equation and the confining pressure and vibration frequency have little influence on the damping ratio. However, the change of damping ratio curve is saltatory with the increase in consolidation ratio. Through the establishment of empirical formula of the test parameters in a certain precision range, the (E_dmax/Pa·k_c)-(σ_m/Pa) curve could be expressed by linear equations after normalization processing, the curve (λ_d/λ_dmax) and (1-G_d/G_dmax) could be expressed by the power function after normalization processing. These functions can be easily used and provide reference for practical engineering.

Key words: civial engineering, clay, hysteresis loop, dynamic triaxial test, dynamic elastic modulus, dynamic shear modulus ratio, damping ratio
