淤泥固化处理以其工艺简单、施工效率高、价格合理等优点,使其在实践中得到广泛的应用。淤泥中加入固化材料后,其物理性能将发生改变,这是因为: 淤泥与固化材料比重不同,有的固化材料比重大于淤泥,有的则相反,两者混合后,改变了淤泥比重;固化材料的加入往往消耗部分水分及有机质,生成新的物质,从而改变淤泥含水率、液塑限及流变性。) 强度。淤泥固化土作为工程填料使用,强度是其最主要的指标,现阶段强度研究主要集中在无侧限抗压强度及抗剪强度等参数。由于淤泥具有高含水率、富含有机质等特点,因此对淤泥固化土的强度影响因素的研究,主要集中在初始含水率、有机质、固化材料掺加量等方面。
Silt solidification treatment is widely used in practice because of its simple technology, high construction efficiency and reasonable price. The physical properties of sludge will change when solidified material is added into it, because: the proportion of sludge and solidified material is different, some solidified material proportion is larger than that of sludge, and some contrary, after mixing the two materials, the proportion of sludge is changed; the addition of solidified material often consumes part of water and organic matter to form new substances. The water content, liquid plastic limit and rheological properties of the sludge are changed. ) Strength. The strength of mud-solidified soil is the most important index when it is used as engineering filling. At present, the strength research mainly focuses on unconfined compressive strength and shear strength. Because of the characteristics of high water content and rich organic matter, the research on the factors influencing the strength of sludge solidified soil mainly focuses on the initial water content, organic matter and the amount of solidified materials.
