摘要

Although it is known that sediments in sewers are not uniform in size, most ofempirical studies were carried out only with uniform materials. An extensive study onthe effect of particle size on sediment transport processes has been carried out at theUniversity of Newcastle upon Tyne - UK and this paper focuses on graded sedimenttransport at limit deposition in clean pipe channel, i.e., the maximum sediment ratethat a flow can transport without any deposition. Analysis of the existing equationsand a new series of 24 tests with uniform material showed that the larger thesediment size the higher the transport rate is. Further some 20 tests with differentmixes with the same median diameter d50 were carried out and the results showedthat the presence of gradation augments the transport rates with the geometricstandard deviation of the size distribution.
