Block Sand Mechanism Experiment and Analysis of Vegetation Flexible Dam

Article Preview

Abstract:

By the indoor flume model experiment, this paper analyzed the block sand mechanism of turbid water appearance. The experiment was done under 1/150, 1/100 and 1/50 three base slopes with 5.09L/s, 9.08L/s and 13.08L/s three discharges. Carried on an observation to the variety that vegetation dam’s in front and back single grain sediment sport speed, and silted up appearance with the sediment in the dam to carry on analysis before the dam to the plant. The experiment showed that the base slope is more big, the damping extent in sport in sediment in upper stream of vegetation dam’s reduce more small, the sediment attains to lose the sand early more equilibrium, and the blocks sand result of vegetation dam is more bad.
