Characteristics of Intercepting Sediment of Debris Flow Check Dam
摘要
Abstract
By using a special experimental devices of debris flow, a seriseof model tests on debris flow passing through check-dem are car ried out. The shape of cross-section of model channel is rectangle with a width 25cm, the gradient is 0～25%. The solid material used in the test are take from Chengdu city, the gravel's maximum diameter is 5cm,10cm,15cm,20cm,25cm, 30cm,35cm.The distance between beam is 1.5cm,2.0cm,3.0cm. The experimental resul ts show that there are 4 main kind of closing conditions, the closing conditions of check dam are closely linked to the ratio b/dmax of distance between be am to the gravel's maximum, and the gradient of channel.关键词
