“…However, through careful model calibrations, an assembly of spherical particles with proper mechanical and physical properties can still be used to simulate the behavior of debris flows. This setting simplifies the complexity of dry granular flow but is also able to deliver a realistic simulation of the interaction between obstacle and flow (Bi, He, & Li, 2016;Cundall, 2008;Karajan, Han, & Teng).…”

“…Lo et al used the PFC-3D software to study the maximum impact of the rock shed suffered by the dry granular flow (Lo, Lee, & Lin, 2016). Bi et al studied the optimization of buffer layer under the impact of dry granular flow by two-dimensional discrete element software, and obtained the optimal thickness of the buffer layer (Bi, He, & Li, 2016). However, the discrete element method is not suitable for investigations of disaster-structure coupled interaction.…”

“…The DEM has been widely used for numerical modeling of rock avalanches (Lo, Lee, & Lin, 2016;Bi, He, & Li, 2016;Cundall, 2008). It is an appropriate tool for modeling rock avalanches because of the discrete nature of materials involved in these phenomena.…”

“…Passive measures can protect infrastructure by blocking or changing the path of landslide movement [3]. Common passive protection measures include shed galleries [5], baffles [6], passive nets, and retaining walls [7][8][9]. Among them, retaining wall is a key structure that can provide reliable protection downstream.…”

Numerical Investigation of Impact Characteristics of Rigid Retaining Wall for Blocking Landslides: A Case Study of the Shum Wan Road Landslide

Landslides pose a serious threat to the downstream infrastructure and personnel safety. For situations where the location of possible landslides is difficult to determine, or the potential landslides areas are widely distributed and scattered, passive protective structural measures need to be adopted to relieve the threat of landslides. Taking the Shum Wan Road landslide as an example, the discrete element method was used to reproduce and analyze the landslide movement. On this basis, this study conducts a further numerical investigation on the impact characteristics of the rigid retaining wall used to block landslides. The results show that the numerical back analysis can well represent the evolution of the landslide, and the numerical results are in good agreement with the actual situation, thus confirming its correctness and effectiveness. Under the condition of setting a rigid retaining wall, the landslide can be effectively blocked and form a final deposition behind the retaining wall. The impact on the rigid retaining wall varies with time, and the distribution of the impact in space is also uneven. Through the statistical analysis of the contact forces on the retaining wall, the distributions of static and peak stresses on the retaining wall can be obtained. Compared with the static stability, the spatial distribution of dynamic impact is more difficult to predict, especially the area of the peak impact has a significant influence on the design. Numerical investigation can efficiently and reliably provide abundant information of static stress and dynamic impact on the rigid retaining wall, which can provide important reference for the optimal design of the rigid retaining wall structure.
