Abstract: At this stage, my country's social economy is changing with each passing day, and the process of urbanization is accelerating, which to a certain extent promotes the development of the construction industry.At the same time, the number and scale of buildings in the city are increasing, and the quality of construction projects is uneven. Therefore, people have gradually begun to pay attention to the treatment of soft soil foundations. Therefore, the strength of soft soil foundations needs to be improved during construction to meet the requirements of the upper part. The structure requires foundation stability and deformation. Based on this, this article discusses in detail the application of soft soil foundation treatment technology in geotechnical engineering, hoping to provide valuable references for relevant professionals in the industry, and then contribute their due force to the healthy and sustainable development of the industry.
