A method employing an aerosol to perform disturbance processing on a soft soil foundation is characterized in comprising the following steps: Vertically providing a drainage channel: the soft soil foundation to be processed is subjected to surveying and setting out, determining the processing area and site leveling according to the requirements in technical code for ground treatment of building; then a plurality of vertical drains are constructed into the soft soil; the top of each of said drains emerges from the surface layer of said soft soil foundation; and said drains are generally referred to as the drainage channel; Providing a bed course and digging a gutter: after completing providing the drain described in the step, the bed course is evenly laid on the surface layer of the soft soil foundation to be processed so as to cover the top of the drain; and the gutter is formed by digging sand around the soft soil foundation to be processed, so as to discharge water out of the site in time; Providing a protective casing or a punched channel: after completing providing the bed course and the gutter described in the step, the protective casing is buried through the bed course and into the soft soil foundation to be processed; alternatively, after completing providing the bed course and the gutter described in the step, a heaped-load is laid on the bed course, and then the punched channel are constructed through the heaped-load and the bed course and into the soft soil foundation to be processed by using punching technique; Providing an injection pipe: after completing providing the protective casing or the punched channel in the step, the injection pipe is passed through the protective casing or the punched channel, and pressed into or drilled into the soft soil foundation to be processed; Injecting an aerosol: connecting the gas inlet of the injection pipe to the discharge of an aerosol generator; then placing an aerosol solution prepared by adding water into the aerosol raw materials in a solid or liquid form into the aerosol generator, opening the switches of the aerosol generator and an aerosol injection apparatus, forming the aerosol by the aerosol solution in the aerosol generator under high pressure, introducing the aerosol into the injection pipe under pressure, injecting the aerosol to the soft soil foundation to be processed by the injection pipe under high pressure; and after injecting to reach the designed range and the designed injection time, lifting the injection pipe to the next design depth for further injecting from low to high step by step until completing all injection operations.
