Taking the second phase ecological seawall of Wenzhou in Zhejiang Province as an example,we conduct physical model tests in a wave harbor pool to explore the mechanical characteristics of a cantilever framed seawall under irregular wave action.We measure the wave pressure values of the vertical wall and cantilever of the seawall under different incident wave conditions,and analyze their time-varying characteristics.Then we obtain the distribution characteristics of wave pressure on the seawall structure under various working conditions,explore the main influencing factors of structural stress,and carry out a redundancy analysis (RDA) on the total wave force and its influencing factors on the structure.The results show that under the action of wave peaks,there is a phase difference in the force acting on the vertical wall of the seawall at different positions in the horizontal direction,and there is a significant difference in the force process above and below the tide level.Under extreme working conditions,the connection between the vertical wall of the seawall and the cantilever is subjected to the maximum pressure.The maximum vertical total force on the entire structure is 5 653.125 kN,which is approximately 70% of the maximum horizontal total force.The correlation between significant wave height and structural stress is greater compared to tide level.In the design of cantilever framed seawalls,it is necessary to ensure the strength of the connection between the vertical wall and the cantilever,and fully consider the impact of vertical wave loads and the occurrence of maximum wave height on overall stability.
