大大小小的土石流含著大量的雨水和泥沙,往房屋旁的道路一路滑落下去,真是有驚無險!Abstract : in light of thicker grain and smaller viscosity of debris flow, a segmented simulation of the debris flow with flume is presented. for the first time. more difficult resistance similarity is brought about by geometric rate without excessive coarsing and discontinuous similarity of sand grain composition in model is eliminated with different grain scale. on this basis the density similarity and sand conveying similarity are achived. the method presented is verified through a model test case
文摘:針對水石流顆粒粗,粘性小的特點,提出了利用水槽進行分段模擬水石流的設想,首次通過幾何變率解決難度較大的阻力相似問題,改變了以往過度加糙的方式;通過變粒徑比尺的方法消除了模型沙級配不連續相似的問題,較好地實現了固體物質級配相似,達到了泥石流的密度相似和輸沙相似.通過水槽概化模型試驗實例,對本方法進行了驗證
