本文根据试验结果,探讨了粗、细颗粒的高浓度悬浮液的流变性质和沉降规律,指出了天然泥沙粗、细颗粒悬浮液物理性质的巨大差别主要起因于颗粒矿物成分的不同,还描述了细颗粒(或料土矿物颗粒)含量很高时悬浮液流变性质的一种异常现象,以及与泥浆流中“停滞层”现象的联系。
Based on the experimental results, the rheological properties and sedimentation rules of high concentration suspensions of coarse and fine particles are discussed. The great difference of the physical properties of crude and fine particle suspensions originates from the difference of the mineral components of the particles. Describes an anomaly of the rheological properties of suspensions at high levels of fine (or earth-mineral) particles and their association with “stagnant” phenomena in the mud flow.
