Abstract: Typhoon exerts great impact on the operation safety of dams in China, especially on the dams in typhoon prone areas along the southeast coast. The impact of typhoon wind on the dam is mainly determined by the wind scale. At present, China Meteorological Administration has realized the prediction of typhoon track and different wind grade radius in the four quadrants of typhoon. The geographic coordinate information database of the concerned dams is established, the typhoon prediction information can be obtained in real time and the later influence range of different typhoon wind scale can be calculated. Based on the dam location and the local wind scale, graded warning is realized. The above-mentioned functions are realized through computer programming. It would quickly identify the dams which may be damaged by typhoon and realize rapid early warning for dams encountering typhoon.
