Ground Anchors

An earth anchor is a devise designed to support structure, most commonly used in geotechnical and construction application. Also known as a ground anchor, percussion driven earth anchor or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance

Earth anchor are used in both temporary or permanent applications, including supporting retaining walls, guyed masts, and circus tents,Once installed and load-locked, an earth anchor exerts efforts to the soil above it, with the soil in turn providing resistance. (5) Upward soil compression created by the anchor is typically exerted in a frustum shaped cone,(6)reflecting:

 The Shear angle of the soil

 The depth at which the anchor has been installed

 The load applied to the anchor

 The size of the anchor and size and angle of its lateral surfaces

When angled these lateral surfaces generate greater cone-shaped soil resistance than a simple cylinder created by purely perpendicular designed
