Figure: Anchored Secant Pile Wall Designed with DeepEX. Use of ground anchors/tiebacks in deep excavations. Anchored walls have become popular in braced excavations because of a) the substantial progress in the technology and availability of high-capacity anchor systems, and b) the absence of interior obstructions that permit uninterrupted earth moving and thus improve the …

In a tangent pile wall, there is no pile overlap as the piles are constructed flush to each other. The main advantages of secant pile walls are: 1. Increased construction alignment flexibility. 2. Increased secant pile wall stiffness compared to sheet piles. 3. Can be installed in difficult ground (cobbles/boulders).

10.1.2 Classification by Construction Method Earth retaining structures (ERS) can also be classified according to the method required for their construction, i.e., fill construction or cut construction. Fill wall construction refers to a wall system in which the wall is constructed from the base of the wall up to the top, i.e.,
