Secant pile walls are being widely employed as retaining structures mostly in the basements. These are generally classified as bulkheads. They are tied back at the top or at a couple of levels depending on the height of retention. Rock anchors are employed for tie backs at the lower levels. This wall is a substitute for diaphragm walls, which requires mobilization of heavy equipment. But secant pile wall was contemplated in a new role at Sundilla. Cut off for the barrage was made in the form of a secant wall. The paper describes the construction details.
