Abstract

The results of a study on the uplift capacity of helical anchors in clay and silt are presented. Full-scale field tests and one-quarter scale laboratory tests were conducted in each soil type. Both field and laboratory tests were performed with anchors installed at various embedment depths. During anchor pullout testing, anchor displacement, anchor resistance, and soil surface deflection were measured. Test results indicate that a similar failure surface developed for all tests. Based on laboratory and field test results, a method for estimating the uplift capacity of helical anchors is presented. Predicted ultimate capacities are compared with observed ultimate capacities for full-scale field tests, and agreement is within 15 to 20 percent.
