摘要
在地质勘查的基础上,分析了大瑞乡泥石流形成条件、基本特征,并计算了泥石流的容重、流量、流速、冲出量等动力学参数,计算证明大瑞乡泥石流属于中频暴雨沟谷型泥石流。根据泥石流的具体情况和当地经济、社会、生态建设的需要,以及被保护对象的重要性,提出了"拦防结合"的防治对策。
Based on the geological investigations, formation conditions and features are studied for the debris flow, Then the dynamic parameters such as bulk density, discharge, velocity and transported sediment scale are calculated. The results showed that the debris flow hazard in Darui country belonged to intermediate frequency ranstorm type debris flow. Based on debris flow hazard features and local social, economic situation as well as need of ecological construction, preventive countermeasures for the debris flow hazards being anti bolcking binding are presented.
