Also need to ensure the wall elements can also take this larger load depending on how you are testing. Usually you're using the wall or capping beam to react the test loads.

Tiebacks/Anchors & Soil Nails

Tiebacks/Anchors & Soil Nails

Anchor Basics • Tieback = Anchor • An anchor is a tension support, which limits movement from subsequent excavation by providing a pre-loaded condition to the supported ground. • Tensile load is transmitted by a steel tendon made of individual strands or bars. The tendon is bonded to competent rock or soil by cement grout.
