Abstract: This paper briefly reviews the history of strong earthquake monitoring at home and abroad, and studies the method and implementation technology of dam strong earthquake monitoring using the Internet technology, and puts forward the concept and method of rapid earthquake damage assessment based on dam strong earthquake monitoring data. The dynamic model test has been carried out for the Three Gorges Gravity Dam. The damage development process of the dam under different earthquake intensity is studied, which provides a quantitative index for the rapid assessment of the earthquake damage of the Three Gorges Dam based on the strong vibration monitoring data. This paper suggests that the important dam strong mo-tion monitoring be constructed as soon as possible according to the specification of strong motion safety monitoring for hydraulic structures. The existing strong motion monitoring equipment should be fully managed by using the Internet technology to ensure its effective and professional operation. The research on the dam failure under the maximum credible earthquake, including the quantified indexes of earthquake damage should be carried out and the expert system of earthquake damage assessment be established. In the event of an earthquake, the monitoring data should be processed rapidly to make a damage assessment and promptly take emergency measures.
