【Abstract】 The cyclic shearing stress induced by earthquake in earth includes cyclic normal stress difference, [σ v σ h] /2, and horizontal tangential cyclic shearing stress, \%τ vh \% In the case of two dimensional plane stress condition, these two components of cyclic shearing stress ordinarily take an elliptical tracking parameter with the time factor during earthquake, but some of tracking parameters are a unique straight line In this paper, the relationship between \%[σ v σ h]\%/2 and τ vh is presented更多还原
