Laboratory Study of Plunging Breaker Wave Force Distribution on a Slender Pile,
Abstract
The dynamic nature of breaking wave forces on structures in the surf zone are considerable. Design of a structure not taking these forces into account can cause both damage to the structure and possibly loss of life. Past studies by previous investigators have contributed considerable knowledge about the makeup and character of breaking wave forces impacting on vertical walled structures, but little study has been devoted to the dynamics of breaking wave forces on a pile. An attempt to develop and test a device which would be of benefit in measuring breaking wave forces was undertaken. An experimental device consisting of several strain gauges positioned inside a small cylindrical, hollow pile section was tested and the results analyzed. Good agreement between this study and results of similar experiments was obtained. This report reviews past and current efforts of investigators studying breaking wave forces on a pile, describes the design and analysis of an experimental wave force measuring device, and presents data collected from actual laboratory studies carried out with the experimental wave force measuring device. This study was performed in the glass walled wave channel in the Hydromechanics Laboratory of Texas A and M University. Keywords: Calibration; Experimental data; and Field tests. (Author)
