Design Analysis of Shallow Embedded Column Foot of Reactive Powder Concrete Pole

摘要

According to the existing specifications, design shallow embedded column foot of 500kV self-supporting partially prestressed reactive powder concrete pole, and perform numerical simulation of column foot stress under actual working condition by using finite element analysis software ANSYS WORKBENCH. Results show that the mechanical characteristic of shallow embedded column foot is good. It can well transmit larger axial pressure, pulling resistance and horizontal force generated by top load of RPC pole. Through the simulation analysis we found that shallow embedded column foot has high safety reliable degree under operation condition, can be used in the current 500 kV transmission lines; In terms of construction technology performance, construction of shallow embedded column foot is simple and quick, can effectively reduce the complexity of construction, shorten the construction period.
