Abstract：When the vacuum preloading method is used to reinforce the flowing mud, the settlement of the foundation is relatively large and the water content is also greatly reduced, but sometimes the vane shear strength is still low, which cannot meet the needs of the project. This is mainly due to the large amount of clay particles and even colloidal particles in this kind of soil particles. The lime mixing method can be used for further treatment when the surface soil cannot meet the engineering needs after treatment of vacuum preloading.
