AI Technical Summary

Technical Problem

Traditional harbor basin structures suffer from wave energy accumulation and reduced energy dissipation efficiency under medium- and long-period wave action, especially under ship shielding conditions where the energy dissipation effect is poor, affecting the stability and safety of the harbor basin.

Method used

The design employs a combination structure of circular caissons and resonant pools. By stacking circular caissons and resonant pools, the design utilizes curved surfaces and staggered placement to reduce wave reflection. Combined with the resonant pool and damping plates, it enhances energy dissipation and optimizes hydrodynamic characteristics.

Benefits of technology

It effectively reduces wave energy accumulation, enhances wave dissipation, ensures stable wave surface in the harbor basin, and safeguards the safety of ship operations. In particular, it can efficiently dissipate energy even when ships are shielded, thereby improving the berthing stability of the harbor basin.

Abstract

This invention provides a circular caisson resonant pool combination structure, comprising an upper circular caisson, a lower circular caisson, and a resonant pool. The upper and lower circular caissons are stacked, with the resonant pool positioned on their rear sides. The wave-facing sides of both the upper and lower circular caissons are arc-shaped curved surfaces, and the top-view outline of the upper caisson overlaps that of the lower caisson. Along the wave-facing direction, the upper and lower circular caissons are staggered with the resonant pool. This invention, through its two-layer stacked circular caisson and resonant pool combination structure, achieves superior stress performance, reduces wave reflection, and significantly weakens wave energy accumulation through scattering, maintaining a stable harbor surface. Addressing the strong penetrating characteristics of medium- and long-period waves, the resonant pool allows the internal fluid to approach a resonant state, utilizing fluid viscosity and vortex structures to dissipate wave energy, further enhancing the wave-damping effect.
