The arch dam is a high-order and ultra-static overall space shell structure on the consolidation and bedrock, and its geometry, boundary conditions and stress state are complex. The three-dimensional finite element solid model of arch dam is established, and the stress and deformation characteristics of the actual dam project are calculated. It is concluded that there is a large tensile stress at the dam at the arch crown section and a large compressive stress at the dam site. The transverse displacement of the body occurs at the abutment of the upstream and downstream faces. The calculation results are in accordance with the stress and deformation characteristics of the arch dam, and the maximum stress and maximum displacement meet the design requirements of the arch dam.
