摘　　要：泥石流是中国常见的一种形成过程复杂和具有较强破坏力的地质灾害,常造成严重的经济损失和人员伤亡。泥石流起动机理的研究既是泥石流灾变机制研究的核心问题,也是泥石流防灾减灾理论与技术研发的基础。系统梳理了土力类泥石流起动机理的已有研究成果,总结了泥石流起动的孕灾条件;对中外学者土力类泥石流起动机理的研究进行了分析与探讨,并分析其优缺点;总结了目前土力类泥石流的起动模型,最后对目前土力类泥石流起动机理的研究不足及未来发展方向进行分析探讨。该研究对土力类泥石流起动机理的研究和促进学科发展具有一定的价值。Debris flow is a common mountain disaster with complex formation process and strong destructive power in China.And debris flow causes serious economic losses and casualties.The research on the initiation mechanism of debris flow is the core issue of the study of debris flow catastrophic mechanism.And the research on the starting mechanism of debris flow is the basis for the research and development of the theory and technology for disaster prevention and mitigation of debris flow.In this paper,the existing research results of the initiating mechanism of soil-mechanical debris flow and the disaster-pregnancy conditions of debris flow initiating were systematically sorted out and summarized.The study of initiating mechanism of soil-mechanical debris flow and its advantages and disadvantages by scholars at home and abroad were analyzed and discussed.The starting model of the current soil-mechanical debris flow was presented.Finally,the insufficiency of the current research on the starting mechanism of the soil-mechanical debris flow and the future development direction were analyzed and discussed.This research has certain value for the study of the initiation mechanism of soil-mechanical debris flow and the development of discipline.
