淤泥固化處理以其工藝簡單、施工效率高、價格合理等優點，使其在實踐中得到廣泛的應用。淤泥中加入固化材料后，其物理性能將發生改變，這是因為: 淤泥與固化材料比重不同，有的固化材料比重大于淤泥，有的則相反，兩者混合后，改變了淤泥比重；固化材料的加入往往消耗部分水分及有機質，生成新的物質，從而改變淤泥含水率、液塑限及流變性。) 強度。淤泥固化土作為工程填料使用，強度是其最主要的指標，現階段強度研究主要集中在無側限抗壓強度及抗剪強度等參數。由于淤泥具有高含水率、富含有機質等特點，因此對淤泥固化土的強度影響因素的研究，主要集中在初始含水率、有機質、固化材料摻加量等方面。
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.
