APPLICATION OF FINITE ELEMENT METHOD TO PULLOUT RESISTANCE OF BURIED ANCHOR

There is a limit in application of the conventional analytical methods by the elastic and plastic theories to complicated soil conditions. The finite element method is capable of considering the nonlinear characteristics of soil and of dealing with a complicated ground condition although problems lie in its analysis, techniques and in related errors. In this study, analyses of the pullout resistance of a buried anchor were performed by a finite element analysis program based on the Lade's constitutive equation to clarify ground stresses and maximum pullout resistance. The results were compared with one of the pullout tests of an anchor by a centrifugal testing machine and the effects of various factors used in the analyses on their results were investigated. The following items have been clarified: (1) the analysis of a shallow anchor requires finer meshes to be taken diagonally from the anchor edge to the ground surface; (2) the Jaky's equation for the coefficient of earth pressure at rest to obtain the initial stress gives a greater pullout resistance for shearing angles less than 35 deg and (3) a region extending to the side more than three times the anchor width must be included for analyzing a shallow anchor.
