Abstract: Introduction In order to solve the problem of insufficient space for steel pipe foundation in urban areas, some optimization methods of steel tube pipe foundation design in space-limited areas are put forward in this paper, which are based on an engineering example. Method Based on the analysis of the mechanical properties of steel pipe foundation and the analysis of the actual situation on the site, some optimization design methods were proposed to solve the problem of insufficient space for steel pipe foundation. Result The actual engineering application results show that this optimization design method has a good effect. Conclusion This paper provides some references for the foundation design of space-limited areas.
