摘要
新河流域位于枣林村2、3、4组北侧,受现有新河大坝保护,历史上记载多次爆发山洪。受5.12地震影响,在暴雨等自然因素的触发下,有暴发较大规模的泥石流发生的可能,对新河大坝的运行安全带来不利影响。根据国内外有关研究成果,结合新河枣林村2、3、4组泥石流的具体特征,分析研究该泥石流的运动特征,包括泥石流的流速、流量和冲击力,这一研究为评价新河枣林村2、3、4组泥石流对新河大坝的影响具有现实意义。
Xinhe river basin is located on the left bank of 2,3,4 group of Zaolin village, protected by Xinhe dam. A lot of evidences show that large scale debris flows had ever occurred along this gully in history time. There exists the possibility of the occurrence of large scale debris flow induced by heavy rainstorms and earthquakes which would threaten the safety of the Xinhe dam. According related research in the oversea or domestic, the authors analyze the dynamic characteristics of debris flow in Xinhe basin incuding flow velocity, flow discharge and impact, which have direct significance to the effect of evaluating debris flow on Xinhe dam.
