四、土工模拟模型及其应用改进的雪撬模型是一种司靠地预测滑坡运动距离的方法。但是关于滑坡危害范围仅仅预测运动距离是不够的,面积预测也需要解决。 Iwasa等人在1980年,Takahashi等人在1986年曾做出了洪水淹没面积预测。Takahashi等人应用同样的方法曾对Nevado del Ruiz火山泥流做过预测。在他们的研究方法中,洪水和泥流都是在二维水平面按流体来对待的,并假定没有摩阻力。所以,在斜坡上运动是 Fourth, the geotechnical simulation model and its application Improved sled model is a kind of Secretary to predict landslide movement distance. However, it is not enough to predict the range of the landslide hazard only and the prediction of the area needs to be solved. Iwasa et al. In 1980, Takahashi et al. Made a prediction of flooded area in 1986. Takahashi et al. Used the same method to predict the Nevado del Ruiz volcano mud stream. In their method of study, floods and muds were treated fluid at two-dimensional levels, assuming no friction. So, moving on a slope is
