摘　　要：海塘是钱塘江河口两岸抵御台风暴潮袭击的重要基础设施,根据天文潮高潮位预报和分析计算,分析研判可能存在的越浪风险,为台风防御提供重要的技术支撑。重点介绍优化后的天文潮高潮位预报模型和不同塘段典型断面结构的风浪计算模型,并提出风险研判模块化应用思路,可为钱塘江河口地区乃至浙江省沿海海塘台风影响下的风浪分析与风险研判提供参考。The seawall is an essential infrastructure on both sides of the Qiantang Estuary to resist the impact of typhoon storm surges.Based on astronomical tide forecast and analysis calculations,an analysis is conducted to assess the potential risks of overtopping waves,providing crucial technical support for typhoon defense.This article focuses on the optimized astronomical tide forecast model and the wind-wave calculation model for typical cross-section structures in different seawall sections.It proposes a modular application approach for risk assessment,offering reference for the analysis of wind-waves and risk assessment under the influence of typhoons on seawalls throughout the province.
