Catastrophic debris flows on 13 August 2010 in the Qingping area, southwestern China: The combined effects of a strong earthquake and subsequent rainstorms
TL;DR: In this paper, a total of 20 debris flows are described in the Wenchuan area in SW China; all were triggered by heavy rainfall on 13th of August 2010, and the debris flows in the area were initiated by run-off erosion on co-seismic landslide material, and concentrated erosion of landslide debris in steep channels; new landslides that transform into debris flows.
Journal ArticleDOI
Effects of near-fault seismic loadings on run-out of large-scale landslide: A case study
TL;DR: In this article, a run-out analysis of the Daguangbao landslides subjected to near-fault multi-direction earthquake forces using discontinuous deformation analysis (DDA) is presented.
Journal ArticleDOI
Development of high-order manifold method
TL;DR: The Manifold Method of Material Analysis with high-order displacement functions has been derived based on triangular meshes for the requirement of high accurate calculations from practical applications and the calculated results are quite good in agreement with theoretical solutions.
Journal ArticleDOI
DDA validation of the mobility of earthquake-induced landslides
Yingbin Zhang,Yingbin Zhang,Jinmei Wang,Qiang Xu,Guangqi Chen,John X. Zhao,Lu Zheng,Zheng Han,Pengcheng Yu +8 more
TL;DR: Wang et al. as discussed by the authors used discontinuous deformation analysis (DDA) to verify the mobility of earthquake-induced landslides, and the results showed that seismic loading could eventually help increase the run-out of landslides.
Journal ArticleDOI
Modeling of landslide generated impulsive waves considering complex topography in reservoir area
TL;DR: In this paper, the wave characteristics in the sliding and channel directions were investigated in detail including the maximum wave amplitude, wave run-up, wave arrival time and wave crest amplitude decay.
