Parametric Study of Uplifting Capacity of Pressure Grouted Helical Anchor in Marine Clay

The pressure grouted helical anchor is an innovative soil-cement using the simultaneous drilling and grouting technique. This paper presents a field study numerical simulation to analyze load-displacement behavior of single anchored in marine soft soil deposit. Three full-scale anchors were tested under monotonic tension loading analysis effect Influence helix plates configuration on lifting capacity. A symmetric three-dimension finite element method (3-D FEM) model was created calibrated based site investigation test data. 3-D FEM utilized examine failure criterion according load diffusion mechanism resistance profile. parametric conducted propose equation for estimating uplift capacity anchors. outcome research will lead development design guidelines clay.
