摘要 邓池沟位于四川省宝兴县境内,在历史上曾发生过几次大规模的泥石流。为了合理地评价邓池沟泥石流对宝兴水电站闸坝的影响,文章在调研基础上,根据国内外有关研究成果,结合邓池沟泥石流的具体特征,对邓池沟不同位置选择了不同的计算公式与评价方法,计算了表征泥石流运动特征的流速、流量和冲击力。结果表明邓池沟再次爆发泥石流将具有较高的流速、较大的流量和冲击力,将会对宝兴水电站闸坝产生严重的危害。 Dengchi gully located in the Baoxing county Sichuan Province.Several large debris flows occurred here in history.In order to evaluate the influence to Baoxing hydroelectric power station reasonably,the author investigated on the spot,and consulted relevant achievements of home and abroad.On the base of those,by using varied formulas and evaluating methods in different locations,connecting with the idiographic characters of debris flows in Dengchi gully,the velocity of flow,the discharge and the impacting power of this debris flow were analysed.It was found that the velocity will be higher,discharge greater and impact more powerful if it accurs again.It may be harmfull to the dam of Baoxing hydroelctric power station.
