Sheet Pile Mooring Wharfs in Soft Ground: Centrifugal Loading Tests

Abstract

Centrifugal loading tests were conducted for an anchor pile-type sheet pile mooring wharf on soft ground by varying the horizontal distance between sheet and anchor piles and changing the number of levels of tie rods. From the test results, we made the following findings: I) The horizontal displacement near the sheet pile crown decreased as the horizontal distance between the sheet and anchor piles increased. 2) The smaller the horizontal displacement at the crown of the sheet piles, the more effective the tie rods worked. 3) When two levels of tie rods were attached to the same anchor pile, the lower tie rods were effective, but the upper ones were not. 4) The part of the sheet pile deeper than a certain depth deformed laterally at about the same mode. However, shallower sections showed various lateral deformation modes, which were dependent on the distance between the sheet and anchor piles.
