Abstract
Provided are an ultra-large bottom opening and closing type three-dimensional loading apparatus and a test method. The apparatus comprises a horizontal reaction frame, a vertical reaction frame, a sample bearing lifting walking beam, lifting cylinders, a reaction support pad beam, array type actuator groups, and a linear array dynamic actuator group. The vertical reaction frame adopts a pre-stressed assembly structure, and the horizontal reaction frame adopts a longitudinal multi-group single-beam circumferential T-shaped scarfed high-strength pre-stressed steel wire winding assembly structure, which meets a high stiffness design requirement of a three-dimensional loading apparatus. The vertical reaction frame cooperates with the sample bearing lifting walking beam, and combines with the reaction support pad beam during test to directly bear test loads, thereby ensuring stability and operational accuracy of equipment during a loading test, and avoiding a lifting risk caused by asynchronous positions of the lifting cylinders.
