With the acceleration of urbanization process, deep foundation pit projects are increasing in the complex urban environment. In view of the challenges of deep foundation pit support technology in the complex urban environment, this paper puts forward optimization strategies from four aspects: support structure selection, construction monitoring, information construction and environmental coordination. Through the rational selection, monitoring and monitoring, the implementation of information construction, the safety and economy of deep foundation pit support can be effectively improved. The research shows that the optimization strategy can significantly reduce the construction risk and provide scientific guidance for the urban deep foundation pit engineering, which has important practical significance.
