本研究从工程角度对MPS方法实际应用模拟雪崩的可能性提出了一些思考。 MPS 方法是再现大规模表面变形流动现象的有力工具。为了将该方法应用于雪崩，我们引入了宾汉姆和膨胀流体的本构方程。侵蚀沉积和空气阻力的影响也被纳入模型中。将修改后的模型应用于一些案例，并通过与实验结果和观测数据的比较来评估模型的性能。
This study presents some considerations on the possibility of practical utilization of MPS method for simulating snow avalanches from engineering points of view. The MPS method is a powerful tool to reproduce flow phenomenon with large scale surface deformation. In order to apply this method to snow avalanches, we introduce a constitutive equation of Bingham and Dilatant fluid. Erosion-deposition and effects of drag force due to air are also incorporated into the model. The modified model was applied to some cases and evaluated the model performances through comparison with experimental results and observed data.
