FULL SCALE MEASUREMENTS OF WAVE ATTENUATION INSIDE A RUBBLE MOUND BREAKWATER

[摘要] At the Zeebrugge harbour (Belgium) a cross-section of the N.W.-breakwater has been instrumented for the study of physical processes related to the behaviour of a prototype rubble mound breakwater in random wave conditions. Within the EC MAST programme (project MAS02-CT92-0023) this monitoring system has been reengineered and extended to a high-quality full scale data acquisition centre (Troch et al., 1995). The development of the prototype monitoring system to a world-wide unique system with respect to the infrastructure available at Zeebrugge, the instrumentation installed on site, and the data management developed, is briefly summarised. Filed measurements of wave attack in front of the breakwater, and pore pressure response inside the breakwater core, have been analysed in order to determine the hydraulic response of the full scale breakwater. Analysis results on wave run-up/run-down measurements, phreatic set-up calculations, and pore pressure wave attenuation are presented here in more detail.
