The CAPWAP solution includes the static total resistance, skin friction and toe bearing of the pile, in addition to the soil resistance distribution, damping factors, and soil stiffness.

Unformatted text preview: The program calculates acceleration, velocities, displacements, waves up, waves down and forces at all points along the pile. The procedure used by CAPWAP includes inputting the force trace obtained from PDA and adjust the soils parameters until the velocity trace obtained from PDA can be recreated. It should be noticed that the opposite procedure (i.e. input velocity trace and generate the force trace) can also be performed. When the match obtained is 26 unsatisfactory, it is necessary to modify the soil parameters, until reaching a satisfactory match results. The process of running CAPWAP is considered an iterative one....
