Abstract: The seismic response of engineering structures is directly influenced by incident site waves, while there are few relevant investigations on the wavefield characteristics. To solve this problem, a source-site medium construction scheme combining the Crust1.0 model and the site condition is developed. The deterministic analysis of the wavefield characteristics at typical engineering sites is performed, and the changes in wavefield information with the source depth, with the epicenter distance, and with the site condition are revealed. The result shows that the incident site waves are numerous and with complex information. There are a small number of large amplitude waves and a large number of small amplitude ones. The wave amplitude decreases with the source depth and the elastic modulus of sites. The large amplitude decreases and the small one may increase with the epicenter distance. The site waves are all with small incident angles distributed in a certain range. For four types of waves formed by the source at the same location, the lower limit is small and the upper limit meets \theta_\mathrmc^\mathrmSP >\theta_\mathrmc^\mathrmSS ≈\theta_\mathrmc^\mathrmPP >\theta_\mathrmc^\mathrmPS . The range of incident angles decreases with the source depth and increases with the epicenter distance and the elastic modulus of sites. For four types of waves, the minimum arrival times meet t_\mathrmf^\mathrmPP <t_\mathrmf^\mathrmPS <t_\mathrmf^\mathrmSP <t_\mathrmf^\mathrmSS . The arrival times gather at the head and disperse at the tail, with the range from 15.2 s to 31.8 s. These factors agree well with the characteristics of actual earthquake records.
