Abstract: Earthquakes, especially strong earthquakes, may easily cause dam accidents. The actual damage of the dam is determined by the earthquake intensity, which is related to the earthquake magnitude, hypocenter depth, geological structure and the distance between the dam and the hypocenter. To realize the graded warning for dams under the condition of earthquake, it is necessary to use the statistical model to quickly calculate the earthquake magnitude at the dam site and compare it with the design standard. By computer programming, the above-mentioned functions can be realized, which can quickly locate the dam that may be damaged by the earthquake and realize rapid early warning for the dam.

Key words:  , dam, earthquake, early warning, safety, earthquake intensity

摘要： 地震尤其是强震及以上地震极易造成大坝失事，大坝实际遭受的破坏程度受地震烈度影响，地震烈度与地震震级、震源深度、地质结构、震源距离相关。为实现地震条件下大坝的分级预警，需利用统计模型快速计算大坝所处位置的地震烈度，并与设防标准进行比对。通过计算机编程实现上述功能，能够快速找到可能遭受地震破坏的大坝，实现快速预警。
