摘　　要：泥石流的发生与否是一个极其复杂的问题,而且是由多种因素共同作用的结果,这也给泥石流活动发展趋势的分析预测带来了困难。主要是在前人研究的基础上,对西南地区某泥石流地区的降雨条件加以分析、研究,从降雨方面,给出该泥石流发生的概率。对该泥石流沟的物源及该泥石流发生后的残留物质做颗粒试验,通过实验结果并结合前人的研究成果,从颗粒级配方面,给出了该泥石流的发生概率。并在最后给出了该论文的主要结论。The happening of debris flow is a complicated problem,and it is the outcome of polysynthesism coaction,this brought difficulty to analytical prediction of development trend of debris flow. The authors analyze and research rainfall of this debris flow area on the base of previous research. The happening probability of this debris flow is given from rainfall. Akernel experiment to provenance of this debris flow ditch and its leftover is made. The happening probability of this debris flow is given from kernel experimentation and previous research, and primary conclusion is obtained.
