摘要
在统计分析对茅洲河口影响较大的风暴潮特征基础上,利用华南近岸ADCIRC风暴潮模型和捷氏风压模式构建了茅洲河口台风暴潮数学模型,并利用3个典型月和10次典型台风对模型进行了参数率定和验证。通过设计不同的台风中心气压、移动速度、最大风速半径、台风路径参数组合,计算得到台风在澳门登陆、行进方向为340°时为可能最大台风风暴潮,并模拟了可能最大风暴潮下茅洲河口的增水过程。计算结果可为茅洲河口工程建设风暴潮防灾减灾提供参考与依据。
Based on the analysis of the statistical characteristics of storm surges which have a great impact on the Maozhou estuary,this paper constructs a typhoon storm surge model based on ADCIRC storm surge model and jetsner wind pressure model,calibrates and verifies the parameters of the model through three typical months and ten typical typhoons,calculates the probable maximum typhoon storm surge when the typhoon lands in Macao with the heading direction of 340°by designing different parameter combinations among typhoon center pressure,moving speed,maximum wind speed radius and typhoon path,and simulates the water augmentation process of Maozhou estuary under the probable maximum storm surge.The calculation results can provide a reference for storm surge prevention and mitigation in Maozhou estuary engineering construction.
