Hydraulic Experiments on Transmission Coefficients for Vertical Structure under Intermediate Water Depth Condition

摘要

Two-dimensional hydraulic model experiments on vertical structures were conducted to investigate wave transmission characteristics under irregular wave condition.The formula about transmission coefficient for the vertical structure was suggested and the results were compared with Goda(1969).Since Goda(1969)’s tests were conducted based on regular waves,the results showed the discrepancy with this study.The Goda’s results were relatively higher than the results from the present study.An influence parameter was quantitatively suggested in this study to consider the effect of structural design factors such as the width of structures,the water depth,and the wave length on the wave transmission,while Goda(1969) suggested the mean,upper and lower limits of parameters for the vertical wall(d = h).The transmission coefficients and energy conservation for zero-freeboard conditions were analyzed.
