摘要:
阵流是黏性泥石流的主要运动形式.选择蒋家沟1987～1994年8年间运动过程完整,阵次明显并且观测资料齐全的50次典型泥石流作为研究对象,讨论泥石流阵流产生的原因,并统计分析泥石流阵流的活动规律和特征.通过对完整的泥石流暴发过程进行分析,发现泥石流阵流径流量与阵流频次之间存在幂律关系;通过对历年典型泥石流流量过程的分析,发现蒋家沟泥石流阵流活动具有多峰性与多时段性.对于进一步认识泥石流(尤其是黏性泥石流)的运动规律和运动特征具有重要参考价值.
Abstract:
Intermittent debris flow is the most important moving form of viscous debris flows.According to field observation materials of debris flow along Jiangjia ravine between 1987 and 1994,50 times typical debris flows with whole occurring process,obvious intermittent characteristics and detailed observation records were chosen as the research object.After analyzing the occurring reasons of debris flow,the rules and characteristics of intermittent debris flow were discussed.As one with whole occurring process of intermittent debris flow be concerned,there exists an obvious power-law relationship between runoff and frequency of intermittent debris flow;as the discharge curve of the intermittent debris flow of the past every year be concerned,intermittent debris flow has the following two characteristics:(1)One with whole occurring process usually has different mounts(usually from one to four);(2)though the largest discharge usually occurs at prophase,it still appears that the largest discharge occurs at more than one stage.This research has reference sense to further recognize the movement rule and characteristics of debris flow(especially viscous debris flow).
