【 摘 要 】

The first priority after a catastrophic earthquake is to carry out emergency rescue for people buried in collapsed buildings. Some large public buildings often have a high concentration of personnel and are the key targets for emergency rescue during earthquakes. This paper summarized four survey methods for the indoor personnel density of key buildings, carried out a sampling survey on indoor personnel density in different time periods in some schools, hospitals, shopping malls, and cinemas in Yanjiao District of Sanhe City in China using these methods, investigated the changing raw of the personnel density in these key target buildings within a period of one day and the changing characteristics of the personnel density in working days and holidays, compared the differences in the time distribution of the personnel density among different types of key targets, and initially explored the strategies and attention points of rescue for indoor personnel in different key targets at different original times of earthquake, thus providing reference for rescue decision-making of indoor personnel in key buildings in the event of a sudden disaster.
