Abstract

The primary question in the debris flow initiation study is differentiation of the initiation process from other processes. This paper introduced a new experimental method and apparatus which can apply artificial rain, detect deformation, resistance and other variables. Based on the experimental data analysis, the definition of debris flow initiation process was promoted and demonstrated. Debris flow initiation is defined as the period in which the strain acceleration of soil mass is greater than zero. The experiment mainly focused on four aspects during the debris flow initiation process: (i) the paper analyzed a series of variables detected by the experiment (strain, resistance, water content and pore-water pressure), (ii)initiation process was defined by the key variable of strain and its propagations, (iii) in order to facilitate further study, initiation process was distinguished into initiation and acceleration processes, (vi) the characteristics of debris flow initiation process was studied. Finally, the experiment results can be used to describe many phenomena such as the abrupt nature of debris flow disasters.
