中文摘要 | 泥石流体中含有从粘粒到砾石的各种粒径的颗粒成份,其级配之宽是任何挟沙水流、高含沙水流所不能比拟的,目前用于泥石流流变研究的各类流变仪,从理论上讲均不可用于非均质流体。但为了实用,在此以前所做的实验多为剔除>2—3毫米的样品,但由于泥石流级配中粗颗粒甚多,其流变数值与实际情况相差很大。为此,寻求能够容纳更粗颗粒的流变仪,已成为泥石流科研工作者孜孜以求之事,苏联于70年代末期曾研制成大型卧式粘度计,并应用于阿尔玛杰克河泥石流样品试验;国内西安冶金建筑学院亦于同期研制成功混凝土砂浆流变仪,并在冶金部有色金属公司矿井回填课题中应用。其改进后的SHL-1型实验样机为我们所引进,并于1984年7月-1985年8月在蒋家泥石流观测实验中使用。共29个泥石流样品,并将其制备成91个实验样品,试验次数182次。得到一批含粒径<20毫米颗粒的泥石流流变资料。 |
英文摘要 | This paper introduced some rheological properties of slurry of containing the sand of bigger particles. SHL-1 modal mortar rheological meter is developed by XiAn college of Metallorgy and Architecture and is type of rotating coaxial cylider. The viscometer has a spate of 45mm between the two cylinders, opeating at a turning speed of 5-300 r. p. m. The biggest grain diarseter is smaller than 20mm.Since 1984, we performed twenty-nine of samples. The remits of our experiments tell us the fact that,1). The Theological value of the same samples will be greatly decreaced as the grain diameter of big particles that have been piked off is reduced (Fig; 1-.3). Fig. 4 may discover that rheological value greatly increased with incres-sement of unit weight of debris flow.2). The same sample will greatly raduce in its rheological value of containing water is increased (Fig, .5-.7).3). For different samples with the same unit weight, but different composition or differeat eoarce-silt content, there will be quite an important difference between the valoe of TB and n, as ahewn Fig ,8-.10.4). The rheologfcal characterietics of debris flow is subjictsd to the influence of content of coarse particles.It will be possible and necessary that explaining fluid properties of debris flow with approaches both Theological and mechni-cal. |
