Ground anchors are retention elements. Their role is to carry and transmit the load into the ground. An anchor is made of steel strands, inserted into in the drilling and has two parts: the free length and the bond lenght.
Ground anchors are most frequently used to support the retaining wall of a deep excavation and can play a permanent or temporary role. When they are no longer necessary, temporary anchors are extracted or de- stressed.
Anchors can be used to perform works for the stabilization of slopes. It is not recommended to use anchors in certain types of grounds: wet sensitive soils, muddy soil and soils that contain organic matter.
