Abstract

In order to explore the characteristics of geological hazards induced by earthquake, the discontinuous deformation analysis (DDA) was used to simulate the failure processes of rock collapses, landslides, and breakwaters under the earthquake loading. Particularly, the influence of the earthquake loading on hazard processes and motions was studied, and new modules were integrated into the current DDA code to obtain the interaction forces. The results show that DDA can be applied to evaluation of landslide mass mobility. The vertical ground motion can remarkably amplify the mobility in the near-fault area. DDA has advantage in the whole-process simulation of landslide induced by earthquake. The simulation results can reflect the characteristics of the failure processes of collapses, landslides and breakwaters faithfully. In addition, DDA is also able to calculate the impact force of failure masses on structures. The peak value of the impact force is much larger than the static lateral pressure, and is four times more than the static lateral pressure in the case study. Hence, the DDA can provide technical guidance for site selection and design of disaster protection from the perspective of reliability and economy.
