| Abstract: | It is necessary to solve the serious problem of flocculation in granulo- metric analysis of fine sediments in order to get correct results in line with Stocks Formula.In this paper the factors giving rise to flocculation of fine sediments in water are analyzed,the flocculating mechanism and dispersing mechanism are discussed,and an antiflocculating physical model is given. Based on a large number of scientific experiments,a complete set ofantiflo- ceulating techniques which consist of both chemical dispersion and physical dispersion are proposed,and thus,some deficiencies of granulometric analy- sis method of fine sediments in current use are complemented and corrected. These techniques have been used for many engineering departments and have proved effective. |
