淤泥固化土的变形包括受力变形和环境变化引起的变形。受力变形包括无侧限抗压强度的破坏应变，三轴试验中不同围压下固化土的轴向应变以及构件的拉伸变形;环境变化引起的变形包括不同龄期、不同条件下的体积变形等。
The deformation of sludge solidified soil includes stress deformation and deformation caused by environmental change. The mechanical deformation includes the failure strain of unconfined compressive strength, the axial strain of solidified soil under different confining pressures in triaxial test and the tensile deformation of components; The deformation caused by environmental change includes volume deformation at different ages and under different conditions.
淤泥固化土作为各类工程的承载基础或砌筑材料，其耐久性是必须考虑的因素。因其属亲水性胶凝材料，受水影响大，因此应考虑水对耐久性的影响，包括抗渗性、抗冻性以及特殊条件下的抗冲刷性、耐腐蚀性等。淤泥固化土抗渗性往往较好，而抗冻性则较差。在影响淤泥固化土力学性能的因素中，往往对耐久性也有影响，力学性质好，耐久性也好
As the bearing foundation or masonry material of various projects, the durability of sludge solidified soil must be considered. Because it is a hydrophilic cementitious material and is greatly affected by water, the impact of water on durability should be considered, including impermeability, frost resistance, erosion resistance and corrosion resistance under special conditions. Silt solidified soil has good impermeability and poor frost resistance. Among the factors affecting the mechanical properties of sludge solidified soil, it often has an impact on the durability. It has good mechanical properties and durability
