In deep foundation pit support projects, the synergistic action of soil nailing walls and prestressed anchor rods is key to ensuring pit stability. Soil nailing walls, through densely arranged soil nails, form a composite with the soil, enhancing the soil's shear strength, while prestressed anchor rods provide additional tensile strength through anchoring force. The synergy between the two can effectively control the deformation of the foundation pit. This paper discusses the mechanism of their synergistic action through theoretical analysis and engineering practice, revealing the mutual influence between soil nailing walls and anchor rods during the stress process. This provides a reference for the design of deep foundation pit supports and promotes the optimization of pit engineering.
