Abstract: Seismic related hazard is frequently encountered in some areas of China. Therefore, in addition to the static analysis of the deep excavation, the seismic stability of the supporting structures also needs to be checked. The finite element analysis is performed on a soil nailing supported deep excavation. The axial stress within the soil nails under the seismic loading are studied. The results indicate that the seismic load controls the soil nail design under the designated earthquake magnitude.

Key words: Deep Excavation, Soil Nailing, Earthquake Action, Dynamical Response
