Experimental Study on Irregular Wave Run-up on Compound Seawall with Steep Bottom and Slow Top
Wave run-up is an important factor that affects the elevation of the top of the seawall and directly affects the investment of the project.The seawall with a steep wall at the bottom,a slope at the top and a platform in the middle is a common seawall cross-section type in the coastal areas in China.The wave run-up under different test conditions is obtained by physical model test.Based on the analysis of the influence of the slope of the steep wall at the bottom of the seawall,the slope of the slope at the top,the width and the height of the platform,and the wave elements on the wave run-up,the calculation formula of the irregular wave run-up is fitted.The results show that when the slope of the steep wall is 0,the wave run-up is smaller than 0.5;When the slope of the steep wall is between 0.03 and 0.05,the wave run-up decreases gradually with the slope of the upper part of the seawall slowing down;With the increase of the platform width,the wave run-up increases,and with the decrease of the platform position,the wave run-up first increases and then decreases.The fitting formula can reflect the law of wave run-up on the section of the mixed seawall with steep wall at the bottom,platform at the middle and slope at the top.
