Taking the 921 earthquake that occurred in 1999 as an example, the earthquake caused severe damage to the Shigang dam in the lower reaches of Dajiaxi, Taichung City. Due to the displacement of the surface, the right bank of the reservoir was lifted by 2.2 meters, causing the reservoir to be 16, 17, and 18 The gate and its related facilities were completely destroyed, and the remaining gates were also distorted. Due to the small amount of water stored in the reservoir during the earthquake, it did not cause a more serious dam breach, but it caused the Taichung area to face water shortage. If the probability of damage to the hydraulic installation can be predicted in advance, there is a preliminary action before the damage occurs. This study refers to foreign literature through finite element analysis and Lagrange equation to simulate dam, reservoir and substrate interactions, through seismic strength and modeling parameters to analyze the vulnerability assessment and prediction of facility damage caused by earthquakes of various intensities. data. Based on the recent 921 earthquake in Taiwan on 1999, the 0206 Meilong Earthquake in 2016 and the 0206 Hualien Earthquake in 2018, the data were analyzed to compare the damages and the analysis results, and the most suitable analytical methods for Taiwan were evaluated.
