Civil Design on 220 kV Underground Substation of Shenzhen Economic Trade Mansion

The 220 kV Underground Substation of Shenzhen Economic Trade Mansion is located in the downtown of Shenzhen city, so the land occupation for the buildings is narrow and irregular, which has brought a great deal of difficulties for the general layout. After comparison of many schemes the substation is designed with a combined building with 6 floors, single floor and two floors, partially 3-floor building for the ground part with steel frame structure. Three floors for the underground part use the shearing wall structure with integral field poured reinforced concrete frame. The reinforced concrete continuous wall has been provided for the outer wall around the basement. The electrical equipment is all placed under the ground the water proof, anti-float design has been enhanced with protective support for the foundation pit.
