A study was conducted on multi-helix anchors for temporary shelters to improve their drivability of without compromising the uplift capacity. Several anchors with varying helix surface geometry were investigated on different types of soils. The tests were carried out on anchors containing solid surface helices, helices with holes and helices with holes and notches on their surfaces. The anchor design has innovative features that minimize the installation force and improve the ease of use of the anchor. Through extensive field and laboratory investigations, the reliability, drivability, ease of installation, and uplift capacity of the anchors were evaluated. The anchors with holes and notches on the helices surfaces performed satisfactorily on their drivability by reducing the driving torque and installation time while meeting the minimum uplift capacity.
