    Helical anchor consist of some steel shafts with a series of helical steel plates welded on a pitch.
    During installation, helical anchor was screwed into the ground by using a standard truck or
    trailer mounted augering equipment. The equipment will apply a rotating moment to the steel
    shafts to screw the anchors into ground. The torque resistance of the anchor will be monitoring
    along the installation. When the torque resistance achieved its designed values, it verified that
    capacity of anchor achieved. Behavior of helical anchor under uplift load in cohesionless soil has
    been studied using previous researches. Based on a few number of laboratory model results many
    investigators reported the uplift loading of helical anchor embedded in cohesionless soil, a review
    of related last works shows that not much research has been done to define the uplift capacity in
    cohesionless soil, a problem that is often encountered in field. The paper observed that the
    ultimate uplift capacity is dependent on the relative undrained/drained shear strength of
    cohesionless soil, the depth ratio of embedment and soil thickness ratio.
