Aiming at the complicated mechanics in the combination structure of double-row piles with arch, a theoretical solution is put forward. Above the bottom of the pit, the differential element calculation model considering the pile-soil effect and the space arch effect is adopted; below the bottom of the pit, the elastic foundation beam model is adopted. Then, by establishing the finite element model, the deformation and stress characteristics of the double-row pile-connected arch structure are analyzed, and the calculation results are compared with the theoretical calculation results. The results show that the theoretical calculation results can be used as reference for engineering design and verification within the allowable range of error.
