摘要:
对2005年8月11日贡嘎山东坡雅家埂河特大型泥石流运动过程进行了描述,并采用现场实地勘查等手段,定量计算泥石流流速和流量等动力学特征,还运用得到的流量反演泥石流运动过程,从而得到雅家埂河特大型泥石流的形成机理。结果表明:雅家埂河特大型泥石流的形成与降雨有直接关系;雅家埂河支沟泥石流的群发性造成主河泥石流规模巨大;经对雅家埂河流域泥石流形成、发生的历史分析,推断出该流域泥石流存在18～21年的暴发周期;雅家埂河松散物源充足,降雨与水源丰富,地形地貌陡峭,极易再次发生规模较大的泥石流。
Abstract:
Motor process of oversize mud-rock flow in Yajiageng River of Eastern Gongga Mountain on August 11, 2005 was described; kinetic characteristics of mud-rock flow were calculated quantificationally with the means of field survey, and was used to simulate the motor process of mud-rock flow in order to find the mechanism of oversize mud-rock flow in Yajiageng River. The results showed that formation of oversize mud-rock flow in Yajiageng River was directly related to the rainfall; mud-rock flow in tributary ditch of Yajiageng River meantime happened, and caused that the flow in the master river was huge; the eruptive period was 18-21 years according to the history of mud-rock flow in Yajiageng River; because loose material was plentiful, rainfall and water were rich and terrain was precipitous, oversize mud-rock flow in Yajiageng River could happen again.
