摘 要
基于大量的实验观察和数据分析研究，简单叙述了实验的过程及方法，揭示了不同粒径固相颗粒在泥石流浆体中的沉降特性。运用设计的实验模型，配置了粘度分别为0.1pa.s、0.3pa.s、0.5pa.s、0.7pa.s4种不同粘度的浆体，筛分出了粒径分别为 ﹑ ﹑ ﹑ 4种固相颗粒，实施了16种试验工况的泥石流沉降试验，获取了多个试验数据。根据实验数据作图，分析对比了相同粒径固相颗粒在不同粘度的浆体和不同粒径固相颗粒在相同粘度浆体中的沉降特性，得到了固相粒径和浆体粘度是影响固相颗粒沉降速度的主要因素，其中颗粒粒径和浆体粘度两者之间也互相影响，固相颗粒的粒径越小，所受到浆体粘度的影响越大。

ABSTRACT
In this paper，according to the study on a great number of experiments and data analyses，another is simply narrated the experiment processes and methods，the settlement characteristics of different sizes of solid phased particles in debris flow is set up. With design experimental model, four different paste viscosity were set ,they were0.1pa.s、0.3pa.s、0.5pa.s 、and 0.7pa.s . Four kinds of solid phased particles were choosed，16 test mode of the settlement of debris flow test was implemented, and it got more than the test data. According to the experimental data plotting, analyzes the correlation of the same size of solid phased particles in the different viscosity paste and different particle size of solid phased particles in the same paste viscosity the settlement characteristics, obtained the solid phase particle size and paste viscosity is the effect of solid phased particles sedimentation velocity of the main factors, among which particle size and paste viscosity both between and influence each other, of solid phased particles size is smaller, paste viscosity by the influence is bigger.
KEYWORDS: Viscous debris flow; Particle size; Paste viscosity; Settling velocity
