Zusammenfassung: | The invention discloses a near strike-slip activity fault geotechnical engineering catastrophe evaluation seismic oscillation determination method, which comprises the following steps of S1, investigating a target work point, and determining a site type and a seismic oscillation level of the target work point; s2, determining seismic oscillation parameters of the target work point; s3, considering the influence of the multidirectionality of the near strike-slip active fault seismic oscillation and the mutual relation between the slope trend and the fault orientation on seismic oscillation determination, and determining the seismic force of the target work point; s4, determining a seismic artery impulse velocity peak value and a pulse period at the target work point; s5, selecting an actually measured seismic record and adjusting a proportionality coefficient of the actually measured seismic record; and S6, carrying out seismic oscillation determination on the target work point by using a time-history analysis |
