Abstract
This paper discusses the deformation and support of deep foundation pit excavation. In the part of deformation mechanism analysis, we make clear the deformation form of deep foundation pit excavation and the influencing factors of deep foundation pit excavation deformation, and further analyze the deep foundation pit deformation mechanism. In the part of supporting structure design, we classified and discussed the deep foundation pit supporting structure, and introduced the method and principle of supporting structure design and recommended supporting structure type in detail. In the part of construction quality control, we analyze the construction technology and quality control points of supporting structure. The research can effectively guide engineering practice and improve the effect of deformation and support during deep foundation pit excavation.
Key words: Deep foundation pit excavation; Deformation mechanism; Supporting structure design
