| 摘 要： | 中兆沟为一泥石流频发地区,曾于1989年和2008年雨季发生较大规模的泥石流,其中1989年泥石流灾情较为严重.本研究在现场踏勘的基础之上,在分析中兆沟泥石流流域分区特征的基础上分别从地形、水源、物源3方面着手,计算泥石流的流体重度、流量、流速、整体冲压力.计算结果显示,中兆沟泥石流为易发性暴雨沟谷泥石流,存在较大危害性.

| Abstract: | The Zhongzhao gully is an old debris flow gully, in which the large-scale debris flows occurred during the rainy seasons in 1989 and 2008,and the disaster in 1989 was more serious. On the basis of the above site visit, the paper analyzes the characteristics of watershed partition and discusses the topography, water source and material provenance of the Zhongzhao gully. The unit weight, flow rate, flow velocity and ram pressure of debris flows are calculated. The results show that the debris flow in Zhongzhao gully is re- garded as a rainstorm dilute debris flow and has high occurrence probability, which can cause great dam- age. |
