… In this paper, we analyzed the effect of artificial viscosity on the landslide flow distance in the Smoothed Particle Hydrodynamics (SPH) method. … It showed that the SPH method considering artificial viscosity could be applied to geo-disasters with large deformation of liquefied ground, such as earthquake-triggered landslides, the lateral spread of liquefied ground, et al. …

… 本研究では,地すべり崩土到達距離の推定手法としてSPH法の適用性を示すことを目的に,荒砥沢地すべりを対象とした2次元の再現解析を行った.流動量が実被害に比べ過少評価される原因として人工粘性を挙げ,その影響を感度分析した.その結果,SPH法による地すべりの流動量評価において,人工粘性が流動量へ影響を与えることを示した.また,荒砥沢地すべりの発生機構として,すべり層で …

… This paper investigates liquefaction induced lateral spreading using a 2D Smoothed particle hydrodynamics (SPH) based numerical method in the framework of fluid dynamics. … Owing to the fact that the induced displacement during lateral spread may reach several meters and the shear strain develops till 100%, a method which is essentially a Langrangian meshfree particle was developed to deal with large displacement. …
