Soft silty soils are widespread on floodplains and have a high natural water content, void ratio, weak permeability (10-10 cm/s), high strength, and low compressive engineering characteristics. Therefore, taking necessary action in areas where these soils are present is vital because they pose tremendous risks to the reliability of engineering. In this paper, the intensity variation rule of cement pile mixing in soft soil on the Wicheng Road, in the city of Wuxi, China, was studied under various unconfirmed compression strength tests, and with different stabilizer mixing agents and ages. For convenience to application to solidified soil engineering, we also confirmed a 28 day predictive model for the strength of solidified soil when different quantities were added, by date fitting using MATLAB. Our experimental results provide a reference for design of soft soil foundations, and show that cement content exerts a large influence on the strength of soft silt soil. The strength of a solidified soil increases linearly as cement content increases. Under conditions where there is a fixed amount of cement, incorporation of fly ash, lime, triethanolamine, sodium chloride, and sand, have different raising effects on the curing strength of silt soil. Indeed, it is important that these additives are mixed in optimal dosages, as too much or too little can augment the impact strength of a stabilized soil.
