| 摘 要： | In this study, a composite source model has been used to calculate the realistic strong ground motions in Beijing area, caused by 1679 MS8.0 earthquake in Sanhe-Pinggu. The results could provide us the useful physical parame-ters for the future seismic hazard analysis in this area. Considering the regional geological/geophysical background, we simulated the scenario earthquake with an associated ground motions in the area ranging from 39.3°N to 41.1°N in latitude and from 115.35°E to 117.55°E in longitude. Some of the key factors which could influence the characteristics of strong ground motion have been discussed, and the resultant peak ground acceleration (PGA) distribution and the peak ground velocity (PGV) distribution around Beijing area also have been made as well. A comparison of the simulated result with the results derived from the attenuation relation has been made, and a suf-ficient discussion about the advantages and disadvantages of composite source model also has been given in this study. The numerical results, such as the PGA, PGV, peak ground displacement (PGD), and the three-component time-histories developed for Beijing area, have a potential application in earthquake engineering field and building code design, especially for the evaluation of critical constructions, government decision making and the seismic hazard assessment by financial/insurance companies.

| Abstract: | In this study, a composite source model has been used to calculate the realistic strong ground motions in Beijing area, caused
by 1679 M
S8.0 earthquake in Sanhe-Pinggu. The results could provide us the useful physical parameters for the future seismic hazard
analysis in this area. Considering the regional geological/geophysical background, we simulated the scenario earthquake with
an associated ground motions in the area ranging from 39.3°N to 41.1°N in latitude and from 115.35°E to 117.55°E in longitude.
Some of the key factors which could influence the characteristics of strong ground motion have been discussed, and the resultant
peak ground acceleration (PGA) distribution and the peak ground velocity (PGV) distribution around Beijing area also have
been made as well. A comparison of the simulated result with the results derived from the attenuation relation has been made,
and a sufficient discussion about the advantages and disadvantages of composite source model also has been given in this study.
The numerical results, such as the PGA, PGV, peak ground displacement (PGD), and the three-component time-histories developed
for Beijing area, have a potential application in earthquake engineering field and building code design, especially for the
evaluation of critical constructions, government decision making and the seismic hazard assessment by financial/insurance
companies.
