利用泥石流专用实验装置，开展了一系列泥石流通过检查模型的模型试验。模型通道断面形状为宽25cm的矩形，坡度为0～25%。试验所用固体材料取自成都市，砾石最大直径为5cm、10cm、15cm、20cm、25cm、30cm、35cm。梁间距为1.5cm、2.0cm、3.0cm。试验结果表明，坝体合闸条件主要有4种，其中坝体合闸条件与梁距砾石最大值的比值b/dmax以及河道坡度密切相关。
By using a special experimental devices of debris flow, a serise of model tests on debris flow passing through check dem are carried 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 gravels maximum diameter is 5cm,10cm,15cm,20cm,25cm,30cm,35cm.The distance between beam is 1.5cm,2.0cm,3.0cm. The experimental results 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 beam to the gravels maximum, and the gradient of channel.
