Ballastless track geometric shape and position change simulation test bed based on pier deformation

The invention discloses a ballastless track geometric shape and position change simulation test bed based on pier deformation, and relates to the technical field of test equipment. According to the equipment, first mounting seats are mounted on the lower surfaces of the two ends of a mounting plate side by side; two rows of ballastless track plates are laid on the upper surface of the beam body; two rows of steel rails are arranged on the upper surface of the ballastless track plate; first mounting seats and second mounting seats are respectively mounted on the inner and outer side surfaces of the steel rails; a first distance sensor is mounted on the first mounting seat; and a second distance sensor is mounted on the second mounting seat. The hydraulic rod is arranged at the bottom of the bridge pier to control the height change of the bridge pier, and the first distance sensors arranged on the two sides of the bridge pier monitor the height change data of the bridge pier; besides, the first distance sensor
