Abstract

New numerical analyses of the vertical uplift capacity of circular anchors embedded in anisotropic and non-homogenous clay are presented in this paper. These analyses are derived based on the lower bound and upper bound finite element limit analysis under an axisymmetric condition. The anisotropic undrained shear (AUS) failure criterion is applied in these analyses. The undrained shear strength of clay increases linearly with depth. The anisotropy is adopted by changing of the ratios between undrained shear strengths determined from triaxial compression test and extension test. The variation of uplift factor (Fc) and shape of failure pattern with three parameters including embedment ratio (H/B), ratio of increasing undrained shear strength with depth (m), and the ratio of anisotropic parameters (re) are verified and investigated. These analyses will provide reliable results in order to improve the engineering calculation for plate anchor embedded in anisotropic and non-homogenous clays.
