Cross-Section Model Test on Shelter Effect of Pile Jetty on Revetment

Pile jetty is a typical type of wharf in construction of port engineering and was often built in front of revetment. The reflected wave height, wave overtopping and pressure were usually reduced because of the barrier effect of upper platform and piles. Cross-section model test was in common use for the verification of structure design. The shelter effect of pile jetty on revetment was tested through cross-section wave physical model. Model scale was 1:20. The results show that the shelter effect is fairly obvious in high design water level. The reduction percentage was 33% of reflected wave height, 50% of wave overtopping and 30-50% of wave loading.
