This research is to predict a hazard area caused by landslides (and friction - dominating - debris flows). A new method has been developed to simulate the motion of landslides and debris flows by combination of soil mechanics and flow dynamics. This new simulation model uses two geotechnical parameters, one is the apparent friction on the sliding surface, it expresses "how far does the londslide move ?",and another is the lateral pressure ratio inside the moving mass,it expresses "how widely does the landslide spread ?". The application of this method to a model sloke and also to the Ontake debris avalanche could give reasonable results,and showed that this method can be a basis for a reliable hazard mapping on londslides

这项研究是为了预测滑坡(和以摩擦为主的泥石流)造成的危险区域。将土力学和水流动力学相结合，提出了一种模拟滑坡泥石流运动的新方法。这种新的模拟模型使用了两个岩土参数，一个是滑动面上的视摩擦力，它表达的是“长滑坡体移动了多远？”，另一个是移动体内部的侧压力比，它表达了“滑坡蔓延的范围有多广？”将该方法应用于一个模型滑坡和Ontake崩塌，均能给出合理的结果，并表明该方法可以为建立可靠的长滑坡危险性地图提供依据
