Experimental Research on the Characteristics of Bamboo Powder Model Sediment

Abstract:

Physical characteristics (including unit weight, dry unit weight and submarine rest angle) and motion characteristics (including settlement characteristics, incipient velocity and resistance characteristics) of bamboo powder model sediment were studied by test in this paper. Experimental study on physical characteristics showed that particle size variation had little effect on unit weight, dry unit weight increased with the particle size,submarine rest angle increased with the decrease in particle size and an empirical formula for calculating submarine rest angle of bamboo powder model sediment was proposed. Experimental study on motion characteristics found that the single particle settling velocity of bamboo powder model sediment increased with particle size, the relative settling velocity initially increased and then decreased with sediment concentration, the incipient velocity increased with the particle size and water depth, the roughness decreased with water depth and increased with the flow velocity and an empirical formula for calculating the incipient velocity of bamboo powder model sediment is proposed.
