The rapid development of urbanization has led to urban problems such as shortage of urban land, traffic jams, and environmental pollution, which seriously restricted the sustainable development of urbanization. The accumulation of heavy metals and organic matter in natural soil not only pollutes the soil and water environment, directly endangers people's physical and mental health, but also causes changes in the nature of foundation engineering, resulting in engineering damage and destruction. Therefore, it is necessary to deal with and control the problem of urban industrial pollution foundation, so that it cannot only meet the needs of environmental safety but also achieve the function of development and utilization.
