Abstract：Hongyang Substation is combined with the upper part of the building of deep buried underground substation, and it can well solve the contradictions between urban electricity and land use tension. However, in power system application, there are fewer researches, and new challenges occur, including coordination and conversion of upper and lower structures, seismic resistance of conversion structure and anti-progressive collapse and other security issues. Various kinds of structure types are compared, and the form of thick plate is selected. The stress and deformation are analyzed by using the finite element software. The whole three-dimensional finite element model of the ground and underground structure of the substation is established by using the mode decomposition response spectrum method. Considering the influences of elastic constraint, horizontal and vertical seismic forces, the seismic performance is designed, and the joint action of the upper and lower structures and the stress and deformation rules of the plate are obtained.
