摘要：
Effective estimation of buried personnel after earthquake is the basis for scientific and orderly emergency response and rescue. Seismic intensity, an imperative data for rapid assessment of post-earthquake personnel buried, plays a crucial role in ensuring the reasonability and accuracy of evaluation results. With the help of intensity calculation results generated in a ground motion attenuation model based on back-projection energy point & shortest distance of earthquake fault, as well as the most widely used elliptical attenuation model at present, this paper firstly carries out a rapid evaluation of buried personnel in three earthquakes with a magnitude of seven or above occurred nearby Gansu province in recent years and subsequently performs a comparison with the actual situation. Compared with the elliptical attenuation model of earthquake intensity, the intensity calculation results based on the back-projection energy point & seismic parameter attenuation model are more capable of determining the distribution of severely afflicted areas and extremely severely afflicted areas accurately and finely,and perfecting the reasonability and accuracy of the total number of personnel buried and classification of key buried areas. The back-projection energy point & seismic parameter attenuation modelhas proved itself with excellent applicability in the rapid evaluation of buried personnel in destructive earthquakes with a magnitude of seven or above, and with fine timeliness to meet the actual needs of earthquake emergency response and emergency rescue. © 2024 China University of Geosciences.
