  2. Tieback (geotechnical) - Wikipedia

    en.wikipedia.org/wiki/Tieback_(geotechnical)

    Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles, sheet piles, secant and tangent walls) to provide additional stability to cantilevered retaining walls. [1] With one end of the tieback secured to the wall, the other end is anchored to a ...

    When used in permanent works, these walls can be designed to resist vertical loads in addition lateral load from retaining soil. Construction of both methods is the same as for foundation bearing piles. Contiguous walls are constructed with small gaps between adjacent piles. The spacing of the piles can be varied to provide suitable bending ...
