“…Many researchers attempted to explore the kinematics of these landslides (Chen et al 2003;Chang et al 2005;Dong et al 2009;Tang et al 2009;Kuo et al 2009;Miyamoto et al 2009;Yano et al 2009). The results indicating the fast moving and long run-out of the giant landslides is dominated by the strength weakening on the slip surface after large displacement of the moving mass with high velocity.…”

Friction characteristics on the sliding surface of giant landslide is important for investigating the triggering, moving, and deposition. In this research, we incorporating a velocity-displacement dependent friction law into the Newmark method to predict the kinematics of a giant landslide. The parameters of the friction law are determined from the high velocity rotary shear experiments of shale and the fault gouge collected from the Tsaoling landslide site triggered by Chi-Chi earthquake in 1999. Based on the strong ground motion data and the account of a survivor, the proposed approach is validated. It is concluded that the Newmark method incorporating into a velocity-displacement dependent friction law can be used to precisely reproduce the detachment, rapid moving, and long run-out of a giant landslide.

“…FSI is a common engineering problem, for instance, the blade of wind turbine is bent in the flapwise direction due to aerodynamic loading [1], the presence and flow of a red blood cell in capillary or arteriole has a significant effect in understanding its microcirculation and regulation [2], the flow pattern of blood in the heart affects the performance of a heart valve [3], in the event of flooding/landslide-building interaction the flood/rock flow potentially gives rise to the collapse of buildings [4], injected CO 2 interacts with reservoir and caprock underground and the interaction can result in unforeseen leakages [5], and vibration-induced buckling is observed in the carbon nano-tubes (CNTs) when delivering fluid flow [6], among many others. This study is concerned with the FSI process involving free surface flow and structural failure, thus a brief review of existing FSI models and their capability or penitential to model such process is discussed first.…”

“…The original version of the PFC was devoted to modeling rockblock systems (Cundall, 1971). It was later applied to the modeling of granular material (Cundall and Strack, 1979;Tang et al, 2009;Salciarini et al, 2009). …”

In China, gravity retaining walls are widely used as protection structures against rockfalls, debris flows and debris avalanches along the roads in mountainous areas. In this paper, the Discrete Element Method (DEM) has been used to investigate the impact of granular avalanches and debris flows on retaining walls. The debris is modeled as two dimensional circular disks that interact through frictional sliding contacts. The basic equations that control the deformation and motion of the particles are introduced. A series of numerical experiments were conducted on an idealized debris slide impacting a retaining wall. The parametric study has been performed to examine the influences of slope geometry, travel distance of the sliding mass, wall position, and surface friction on the impact force exerted on the wall. Results show that: 1) the force achieves its maximum value when slope angle is equal to 60°, as it varies from 30° to 75°; 2) an approximate linear relationship between the impact force and the storage area length is determined.
