Behavior analysis of single strut arched retaining structure in foundation pits

The behavior of single strut arched retaining structure is analyzed. The influence factors include the deformation of arch foot pile, the embedded depth, the characteristics of soil under the bottom of excavation, the shape of arch, the position and the stiffness of strut, the stiffness of buttress and the distribution of soil pressure. The influences of these factors, which are important to guide the design and application of single strut arched retaining structure, are described in detail in this paper.
