Disclosed is an oil pressure type seismic mitigation and isolation support and a use method thereof. An upper plate slot is arranged above a lower plate slot, the lower part of the upper plate slot and the upper part of the lower plate slot are both provided with grooves, and the upper part of the upper plate slot and the lower part of the lower plate slot are both provided with embedded bars; a steel cushion body has a shape of a cuboid and is arranged on the upper surface of a seismic mitigation layer, the seismic mitigation layer is arranged in the groove at the upper part of the lower plate slot, and the upper part of the steel cushion body extends into the groove of the upper plate slot and is in contact with the bottom surface of the groove one-direction double-direction.

Oil pressure type seismic mitigation and isolation support and use method thereof

Disclosed is a system and method for testing a structure mode of vibration based on digital image recognition, which comprises a camera, targets, a bridge, a vertical acceleration sensor and a lateral acceleration sensor; the camera is arranged near the bridge head of the bridge; the bridge is equipped with a plurality of targets equidistantly inside guardrails on both sides; and the vertical acceleration sensor and the lateral acceleration sensor are fixedly arranged on the camera. The present application avoids the arrangement of a large number of sensors and complicated wiring in the bridge vibration detection, saves time and reduces economic cost, is convenient to operate, has relatively high precision, and has broad application prospects.
