摘　　要：随着大沽河排污综合治理工程的全线开工,由此产生的大量淤泥的处理、处置任务十分艰巨,也很大程度上决定了河道治理的最终效果。尝试将清出淤泥处理后用于公路路基垫土,以实现其资源化和无害化利用的目的。试验结果显示,淤泥经石灰、建筑废料等材料拌混后,压实度和加州承载比(CBR)参数可以满足部分路基填筑要求,其重金属浸出结果符合环保要求。该方法具有消化容量大、处理简单快速等优点,可以直接消纳高含水率淤泥。When the comprehensive treatment project of Dagu river starts working,how to deal with big volume river sludge is difficult and its results would affect project purpose.The paper tries to use the treated sludge to fill subgrade in order to get the purpose of resource and innocuity.The experiment results show that the compaction and California Bearing Ratio(CBR) of sludge which is mixed with calcareousness and construction wastes can meet the need of filling subgrade and its heavy metal lixiviating result can also answer for environmental requests.The way of filling subgrade can directly treat high containing water sludge and has the excellences of big digestion capability and rapid & simple treatment.
