摘　　要：在岳阳市中心城区污水系统综合治理项目中,通过在实验室中模拟添加水泥基固化材料进行固化处理,研究处理后底泥的各项指标参数,研究表明淤泥经过水泥基固化处理后,可作为路基填料,同时结合实际情况,提出适用于路基填土的淤泥固化资源化设计与施工方法,解决疏浚工程底泥资源化利用的问题。In the project of the comprehensive treatment of sewage system in the urban center of Yueyang City,by adding cement-based materials of solidification to solidify in laboratory simulations,this paper studies the various index parameters of the silt after the treatment. It shows that the silt can be used as the material for filling up subgrades after the cement-based treatment of solidification. Meanwhile,applying to the actual situation,the design and method of construction for solidifying the resource of sludge used to fill up subgrades are put forward,so as to solve the problem concerning the utilization of the resource in projects of dredging sludge.
