| 中文摘要: |
| 广东省是中国沿海最为发达的省份之一，人口密度大，经济总量多，受台风影响严重，每年台风都给这里带来重大经济损失。本文通过对广东省以25公里的距离来划分正方形网格，再以每个网格点为中心，提取台风，并分析各点台风关键参数概率模型。最后利用Monte-Carlo数值模拟方法和Yan Meng风场进行模拟计算，得到各点重现期100年的台风极值风速，并绘出广东省风速分布图，为抗风设计提供参考。 |
| 英文摘要: |
| Guangdong province is one of the most developed provinces in coastal areas of China. The population density and economic aggregate here are very great. So every year when the typhoon comes, the province is influenced seriously. In this paper, Guangdong province is covered with a nest grid with spacing 25 Km. Using typhoon data of each grid, the probability distributions of key parameters are extracted. Then the extreme wind speeds of 100 years return period are calculated by Monte-Carlo simulation method and Yan Meng wind field model. At last, a new map of wind speeds which can provide a reference for wind-resistant design is proposed |
