Design method of substation assembled concrete independent foundation
To further promote the modular construction of substation,the cast-in-place concrete independent foundation in substation project is used as a prototype to analyze its force characteristics and foundation form,and the assembled block and connection design of the foundation is carried out,and the bearing capacity and crack resistance of the designed assembled foundation is verified through ABAQUS finite element simulation and relevant specification formula.The results show that the design of the blocks is reasonable and can meet the requirements of factory fabrication,transportation and lifting;the prestress-shear key connection method is suitable for the assembled concrete foundation,and the designed prestressed tendons and shear keys meet the requirements of bending and shear bearing capacity and crack resistance of the foundation joint surface,and have a certain safety reserve.
