港珠澳大桥珠澳口岸人工岛填海工程海堤越浪量的优化设计

为安全可靠地降低防浪墙顶高程,在分析国内外规范对越浪量标准界定的基础上,为港珠澳大桥珠澳口岸人工岛填海工程海堤拟定了运营工况、设计工况和校核工况这3种工况组合和相应的允许越浪量标准,结合物理模型试验,对海堤越浪量进行优化设计,使人工岛地面与挡浪墙之间的高差减少到人体正常身高范围,可为过境旅客提供海天一色的景观视线。

Optimal design of wave overtopping of seawall for Hongkong-Zhuhai-Macau bridge Zhuhai-Macau frontier port artificial island reclamation works

In order to reduce the top of the seawall elevation safely and reliably, we analyze the domestic and international norms of the tolerable overtopping limit, and study the operation condition, design condition and check condition and corresponding tolerable overtopping limit for three conditions for Hongkong-Zhuhai-Macau bridge Zhuhai-Macau frontier port artificial island reclamation works. Combining the physical model test, we carry out the optimal design of wave overtopping of seawall. By controlling the height difference between the artificial island ground and the top of the seawall elevation in the range of normal human height, we can offer well sky and sea view for passengers.
