泥石流是山区沟壑中含沙量最高的自然径流.世界上含沙量最高的河流,我国的黄河及其一些支流,年平均含沙量500公斤/立方米,最大含沙量达1500～1600公斤/立方米,被称为高含沙水流~[1],其含沙量也不及泥石流.泥石流不但含沙量更高,而且颗粒要粗大得多.根据我们目前测得的资料,泥石流容重最大值可达2.372克/立方厘米, Debris flow is the highest sediment concentration in the mountainous gully, the highest sediment concentration in the world, the Yellow River and some of its tributaries in China, with an average annual sediment concentration of 500 kg / m 3 and a maximum sediment concentration of 1500-1600 kg / M3, known as the high sediment flow ~ [1], its sediment is less than the debris flow debris flow is not only higher, but also much larger particles.According to our current measured data, debris flow capacity of the largest The value of up to 2.372 grams / cubic centimeter,
