Abstract— Sedimentation column that the size of100×500mm is used to study the relationship between the self weight settlement of cohesive soil and the initial sand-mud ratio and initial water content of dredger fill of clay soil mixing sand. Test results show that:(1) the consolidation time of dredger fill of clay soil mixing sand is mainly related to the size of the settlement column, compared with the initial water content, the influence of sand-mud ratio is not significant. The larger the size of the settlement column, the longer time of gravity consolidation will be completed, and the higher initial water content, the shorter time of consolidation. (2) The settlement curve of dredger fill of clay soil mixing sand is in accordance with the relation formula .In the formula, is the steady settlement. The stability time of settlement consolidation can be deduced by this formula. Under the condition of the same water content, the consolidation settlement of dredger fill of clay soil mixing sand increases linearly with the sand-mud ratio, but the amplitude of the increase is not large; (3) the logarithmic curve of consolidation settlement is basically divided into three stages: The straight line segment, the upper concave line segment and the lower concave line segment. At first, the slope of the linear section increases gradually with the increase of the initial water content; The upper concave curve gradually decreases with the increase of water content, and when the initial water content reaches a certain value, the concave curve becomes a straight line; The lower concave curve section gradually changes to the curve type, then the slope of the settlement curve decreases and finally tends to the horizontal.
Keywords— clay soil mixing sand; self weight consolidation settlement; initial water content; initial sand-mud ratio.
