由于泥石流也是一种流体,因此以往的泥石流研究中,主要是水力学工作者从水力学的角度进行.然而到了近年来泥石流的研究工作有了突破已从单纯的流态研究转移到泥石流发生机理的研究,为此就必然要涉入土力学的领域.笔者在泥石流实地考察和模型实验的基础上,就泥石流的发生过程以及用土力学判断泥石流是否发生的问题,建立了如下的假定模型;并将这假定模型试用于因滑坡而引起的龟濑小规模泥石流和高知市园行寺的大规模泥石流的分析,本文正是这种尝试获得令人满意结果的总结报告.
Since debris flow is also a kind of fluid, in the past studies of debris flow, mainly hydraulic engineers proceeded from the perspective of hydraulics, but in recent years, breakthroughs in debris flow research have shifted from purely fluid state studies to debris flow generation mechanisms Therefore, it is bound to be involved in the field of soil mechanics.On the basis of field investigation and model experiment of debris flow, the author establishes the following assumption model on the occurrence process of debris flow and soil mechanics to judge whether debris flow occurs. This paper assumes that the model is amenable to the analysis of the large-scale debris flow caused by the landslide and the large-scale debris flow of the Tsukasa-ji Temple in Kochi. This is a summary report of satisfactory results from this attempt.
