| 摘 要： | 三岔河流域高山带裸露的岩石地表与其35°以上的陡峻地形一同构成了迅速汇流的有利条件;夏季高山带5℃～10℃左右的持续高温天气过程,引起冰舌末端发生冰体崩解或山缘积雪发生雪崩?进入沟道,并在较短时间内融化,形成激发泥石流的冰雪消融洪水?目前,由于提供泥石流的这种水源和沟道内丰富的松散固体物质条件依然具备,所以,泥石流爆发将仍处于活跃发展阶段?

| Abstract: | The benefical conditions that debris flow is formed in Sanchahe valley along Du-ku highway of Tianshan mountains are frequent rainstorm,exposed rock and high and precipitous land form in alpine region of the drainage basin. Sustained high air temperature in summer can lead to ice-fall of glacier at backwall of the basin.Then,the ice-fall is melted qulkly and results in formation of glacier flood which the debris flow is simulated.Because the conditions mentioned above are still exist,debris flow at present,is in an active period |
