Seismic Triggering

Landslides are often triggered by earthquakes and can cause immense damage due to large mass movements. To model such large-deformation events, the material point method (MPM) has become increasingly popular in recent years. A limitation of existing MPM implementations is the lack of appropriate boundary conditions to perform seismic response analysis of slopes. In this article, an extension to the basic MPM framework is proposed for simulating the seismic triggering and subsequent collapse of slopes within a single analysis step. Original implementations of a compliant base boundary and free-field boundary conditions in the MPM framework are presented, enabling the application of input ground motions while accounting for the absorption of outgoing waves and the free-ground movement at the lateral boundaries. An example slope is analysed to illustrate the proposed procedure and to benchmark it against the results obtained using an independent simulation technique, based on a three-step FE analysis. The comparison generally shows a good agreement of the results obtained from the two independent procedures and highlights advantages of the presented “all-in-one” MPM approach, in particular for long duration strong motions.

In this paper, using finite element software ANSYSanalyzes seismic respons of Fuyang river aqueduct, respectively establishfinite element model under viscoelastic boundary conditions and elasticboundary conditions, compare and analyze seismic respons of aqueduct structureunder two kinds of boundary conditions. The results show that, compared withelastic boundary conditions, viscoelastic boundary conditions not only cansimulate elastic recovery performance of foundation, but also can realizeinfinite medium radiation damping, and viscoelastic boundary conditions is moreclose to the actual situation.
