Abstract
The extremely strong Wenchuan earthquake triggered thousands of landslides in Sichuan Province, China. Flow-like landslides, such as the Tangjiashan, Wangjiayan, and Donghekou landslides were among the most destructive, causing many casualties and serious economic damage. In this chapter, a three-dimensional SPH model was introduced and numerical modeling of the propagation of the Tangjiashan, Wangjiayan, and Donghekou landslides was performed. The whole flow processes of these flow-like landslides across the 3D terrain are represented. Time-history curves of the velocity and displacement were obtained to analyze the movement characteristics of the landslide mass. The shapes of the deposition zones after slide occurrence were investigated. The prediction of the fluidization characteristics of earthquake-induced flow-like landslides can notably reduce sudden loss of life, as it provides a means for mapping hazardous areas, for estimating the hazard intensity, and for identification and design of appropriate protective measures.
