    Abstract

    The use of the disk spring pile cap, consisting of a contained group of several stacked disks, because of its high spring constant and high recovery coefficient, can raise pile driving construction efficiency. In order to reach the optimum effect, however, the proper spring arrangement in the stack, the proper composite spring stiffness, and the proper spring recovery coefficient must be selected. The authors have carred out an optimization analysis of these disk spring parameters in order to find the most appropriate set for effective pile driving under given conditions.
