07. Ground Anchors
Ground anchors and tiebacks are often the same thing. A ground anchor can be a vertical element, which holds down a
structure, or a tieback element, which holds back a retaining wall. Ground anchors are versatile way to retain a earth
retention system. The anchor acquires its capacity through frictional resistance with the rock into which it is grouted.
When placed through an H-beam or concrete wall, tensioned and locked down, it is a high capacity anchor for the retention system.
When the rock is shallor, this is most often the preferred method of tieback.
There are other forms of tiebacks that include dead man anchors and soil anchors.
A dead man is a large block of concrete that a tieback is attached to for anchorage.
A series of grouting creates a bulb effect on the bond length of the anchor. This
bulb is what creates the friction on the soil to hold the tension loads.
