WAVE EQUATION ANALYSES OF PILE DRIVING
The one-dimensional wave equation analysis has been found to be superior to dynamic formulae and other available numerical techniques for analyzing impact pile-driving behavior. The results are usually acceptable for selection of efficient hammer-pile-soil systems; somewhat limited success has been attained in predicting pile bearing capacity, particularly for piles in cohesive soils. The most successful applications of wave equation solutions have involved the selection of compatible driving equipment and determination of pile driveability. Evaluation of peak driving stresses has reduced the incidence of pile breakage. Computer programs from Texas A&M University were adapted to computer facilities at the U. S. Army Engineer Waterways Experiment Station. The wave equation theory was reviewed, and analytical solutions based on one-dimensional theory were described. Examples of wave equation applications to practical engineering problems are presented. A time-sharing version of the Texas A&M design-oriented computer program is listed and usage guidelines are provided.
