Ground Anchoring – Effective Technique Used To Secure Structure from Lateral/Vertical Forces
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 11
Abstract
An earth anchor is a device designed to support structures, most commonly used in geotechnical applications. Also known as a ground anchor, earth anchor or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and force-resistance characteristics. They are used in both temporary and permanent applications. Ground anchors are effectively restraining devices used in many different types of structures including retaining walls, dams, wharves, bridge abutments and foundations for buildings. Ground anchors are stressed to prevent structural movement and they typically transfer their load over a fixed length. These are commonly referred to as tension anchors and are suited for strong rock conditions. For anchors founded in soil or weak rock, load distributive compressive and tension anchors are used as they have small successive bond lengths rather than one unique longer bond length. Ground anchors consist of a specific anchoring assembly designed to transfer home anchoring loads to the ground are are used extensively in manufactured home installations. Ground anchor movements of several inches can have significant negative impacts on long-term performance. In cohesive soils, such anchor movements in a vertical direction can approach or exceed the soil’s shear strength. In such cases, the ground anchor is supported by the soil’s residual shear strength, resulting in a decrease in anchor capacity.
