摘　　要：海堤越浪影响护面块体和堤顶道路稳定,是临海工程建设需考虑的重要因素。以巴基斯坦瓜达尔港东湾快速路路基工程为例,对于“一带一路”沿岸海洋水文资料匮乏地区,利用再分析数据推求工程海域设计波要素,并采用短期实测波浪资料进行修正,利用SWAN波浪数学模型构建近岸二维水动力模型,推求工程位置极端高水位与设计高水位下工程区的设计波浪要素。基于计算的特征波浪,就东湾快速路(临海侧)工程建设面临的堤顶高程及其越浪量、防浪墙和护面块体等结构稳定性等问题开展了波浪断面物理模型试验研究,针对试验过程中护脚棱体的块石有位移、上抛失稳等现象,提出了优化措施,为沿海道路工程设计提供借鉴和参考。The impact of seawall wave overtopping on the stability of armor blocks and embankment roads is a crucial consideration in coastal engineering projects.Taking the subgrade project of the Gwadar Port Eastern Bay Expressway in Pakistan as an example,for the areas lacking marine hydrological data along"the Belt and Road",the design wave parameters of the engineering sea area were deduced by using the reanalysis data,and the short-term measured wave data were used to revised.By employing the SWAN wave model to construct a two-dimensional hydrodynamic model of the nearshore area,the design wave parameters of the project area under extreme high water level and design high water level were deduced.Based on the derived wave characteristics,physical model tests of wave section were conducted to address the embankment top elevation,wave overtopping discharge,and the stability of structures such as wave barriers and armor blocks for the Eastern Bay Expressway(coastal side)construction.In response to observed displacement and instability issues with the banket blocks during testing,optimization measures were proposed to provide reference for coastal road engineering design.
