Synthesized Near Field Ground Motion in a Shallow Basin
Abstract eng: Near field ground motion in a shallow basin from strong earthquake occurred on a blind fault beneath is synthesized in this paper. A hybrid source model is adopted, which combines Asperity model and K square model. The ground motion at high frequency range is synthesized by a random method with dynamic corner frequency. Two steps are carried out to calculate the low frequency motion. Analytical Green Function Method is for the deeper part of the crust with source and 3D wave propagation finite element method is applied for the shallower part. The ground motion in the basin is further calculated by means of 1D equivalent linearization method at each node of calculation network. The spatial relativity of the ground motions at nodes next to each another in the basin is finally analyzed.
