Abstract
Transformer is key equipment in the power transmission and transformation system. When the seismic calculation is carried out, the foundation soil is generally considered to be absolutely rigid, and the bottom of the structure is considered as the fixed end, the soil-structure interaction is ignored. This paper is aimed to study the soil-structure interaction’s impact on the seismic performance of the transformer and other power facilities by carrying out cyclic shear test on cohesive soil, simulating the dynamic response of clay soil under the seismic load, and get the nonlinear dynamic characteristics parameters of the soil in the loading process of seismic cycles. On the basis of the study, the fitting equation of the dynamic shear modulus and damping ratio of the soil is put forward through analyzing the cohesive soil dynamic hysteresis constitutive model.Keywords
