Generally sediment-water mixture of hyperconcentration belongs to category of Bingham flind. Because of limitation of experimental conditiin and complexity of affecting factors, data of systematic experiments and investigations on Bingham yield stress of sediment-water mixture were r ther less and inconsistent by various authors. In this paper results of rheological tests on the sediment-water mixture of hyperconcentration are given .11 samples with different grain size distribution ( d= 0.001 - 0.16mm ) and volumetric concentation ( Cv =0.07 - 0.43 ) are taken for the tests. The results of experiments were analyzed by the concept of "maximum concentration" which behaves Property of grain size di-stribution of the sediment. A unfied empirical formula of Bingham yield stress for sediment-water mixture has developed which is expressed as function of maximum concentration Cvm and volumetric concentration Cv of solid. A primary relationship among yield stress, the grain size distribution, concentr tion of solid and flow Property of sediment-water mixture has also been discussed in this paper.

高浓度浑水一般属宾汉体。由于试验条件及浑水流变特性的复杂,对浑水的宾汉极限剪应力的系统研究很少,现有试验成果很不统一,多数不能反映浑水中固体颗粒组成对宾汉极限剪应力的影响。本文通过应用毛细管粘度计对十一种混合沙作了流变试验,以反映颗粒级配特性的“极限浓度”及固体体积浓度为参数,求得浑水宾汉极限剪应力的统一表达式。文中并就极限浓度对非牛顿体形成条件及对非牛顿体由两相过渡到一相体的影响等向题,提出初步的经验关系。讨论了宾汉极限剪应力与固体体积浓度、颗粒级配特性及浑水流态之间的综合关系。

In engineering operation, erosion of solids is a factor that cannot be ignored as it reduces the life and efficiency of machine and tool. Quantitative measurement of this wear is needed to study its law and to combat it. The authoers designed a hexagnal device for testing solid erosion and analysed its working principle and wear mechanism A lot of tests were made to study the effects of operating parameters of the tester, such as solid size, solid content and solid impact rate. Based on this a testing standard is presented Erosive wear of various rock grains was measured with this standard. Conclusions can be drawn from all the work that the hexagnal device is portable and easy-handling. It has minimum measuring error and good repeatability, and can be used as a tool for testing solid erosion. The tester application can also be expanded by adjusting operation parameters or/ and by changing testing materials to measure solid wear under different conditions and wear resistance of various materials.
