Experimental study on bearing capacity of prestressed prefabricated foundation
In the process of transmission line engineering application,some areas are greatly affected by temperature and wind load,which is difficult for seasonal mass concrete construction.In view of the above engineering difficulties,a new scale model of prestressed prefabricated foundation with a ratio of 1:2 was designed and made,and the mechanical properties of this scale model was experimentally studied under monotonous and reciprocating loads.Then,the software ABAQUS was used for numerical simulation analysis,and the results of numerical simulation were compared with the test results.The results show that under monotone load,the foundation fails when applied to the design load,and the failure mode is that the upper flange of the foundation is detached from the foundation column.Under the action of reciprocating load,the flange of the lower part of the foundation column is separated from the bottom plate,and the concrete cracks.The prestressed prefabricated foundation has good bearing capacity and resistance to deformation under the action of design load.
