Method for connecting prefabricated T-shaped pier through unbonded prestressed tendons and steel bars

The invention discloses a method for connecting prefabricated T-shaped piers through unbonded prestressed tendons and reinforcing steel bars, and relates to the technical field of subway systems, urban fast rail systems, light rail systems, medium-low speed maglev traffic systems, straddle type monorail systems and the like, and the prefabricated T-shaped piers comprise pile foundations, bearing platforms and prefabricated T-shaped piers. The construction time is saved, the construction technology is optimized, then the effects of reducing the influence on existing road traffic, shortening the construction period and improving the production efficiency are achieved, the unbonded vertical prestressed tendons in the unbonded state can release vibration when the pier vibrates, then the damping effect is provided, and the construction period is shortened. The rigid damage of bridge vibration to the pier is reduced, the overall anti-seismic property of the pier is improved, the pier is suitable for a section with
