摘　　要：研究了不同化学药剂配比对疏浚淤泥脱水固结效果的影响,以含水率和无侧限抗压强度作为评价指标,主要研究了硅酸盐水泥、氧化钙、聚丙烯酰胺的不同配比对疏浚淤泥脱水固结效果的影响,并展望了脱水固结药剂的发展前景。结果表明:在疏浚淤泥含水率相同时,硅酸盐水泥5%、氧化钙10%、聚丙烯酰胺1%的脱水固结效果最佳;在药剂配比相同时,疏浚淤泥含水率调整为120%时,脱水固结效果最好。The influence of different chemical agent ratios on the dewatering and consolidation effect of dredged sludge was studied.Taking water content and unconfined compressive strength as evaluation indicators,the influence of different proportions of portland cement,calcium oxide,polyacrylamide on the dewatering and consolidation effect of dredged sludge was investigated.The development trend of dehydration and consolidation agent was prospected.The results showed that when the water content of dredged sludge was the same,the dehydration and consolidation effect of portland cement 5%,calcium oxide 10%,and polyacrylamide 1%was the best.When the agent ratio was the same,the dehydration and consolidation effect was the best when the water content of dredged sludge was adjusted to 120%.
