Abstract

Various numerical analysis methods have been developed to simulate earthquake-induced slope failures. Simulations of earthquake-induced slope failures require capabilities to reproduce some factors, including the trigger level of an input ground motion and a travel distance of debris. For reproducing a trigger level of an input motion, the finite element method based on solid mechanics has been used. For reproducing a travel distance of debris, simulation methods based on the fluid dynamics have been applied. This study presents a new approach to simulate an earthquake-induced slope failure, coupling the solid mechanics and the fluid dynamics, based on the framework of the smoothed particle hydrodynamics (SPH). The presented approach allows us to simulate an earthquake-induced slope failure from its triggering stage to its accumulation stage. The presented approach demonstrated its capabilities to reproduce the trigger level of ground motion and a travel distance of debris through several simulation cases. The paper concluded that the presented approach could be a promising method to simulate earthquake-induced slope failures.

Microzonation of Seismic Parameters in Geological Formation Units Along the Opak River Using Microtremor Measurements

“…In various studies, Kg represents the impact of seismic wave propagation in terms of damage to building structures, liquefaction, and local site effects [33][34][35][36][37]. The K g values in the Opak River area range from 0.01 to 20.25 (Fig.…”
