Numerical analysis of the effect of embedment depth on the geometry of the cone failure

Abstract This paper presents the results of a numerical FEM analysis effect embedment depth on extent failure zone (cone failure) under an undercut anchor. For establishment other affecting quantities, formation value cone angle rock medium depending was analysed. The problem is interesting as regards aspects mass loosening during pull-out anchors. As result analysis, significant propagation and has been found. increasing significantly decreases measured free surface. limits potential interaction zones in multi-anchor systems.
