To provide a loading test apparatus capable of grasping an attitude of a reaction girder, and a loading test method.
A test pile 12 is buried in ground 20; and a jack 16 for adding a vertical load is provided on the top surface 12U of the test pile 12. The reaction girder 18 is placed on the jack 16; and a reaction force of the jack 16 acts on the central portion of the reaction girder 18. Reaction piles 14 for receiving the reaction force of the jack 16 are buried on both the sides of the test pile 12, respectively. A capping material 30 is fixed to an upper portion of the reaction pile 14, and coupled to both ends of the reaction girder 18 via the capping material 30 by means of a steel rod 22. A displacement measuring instrument 32 for the reaction girder is attached between the reaction girder 18 and the reaction pile 14. An upper portion of the displacement measuring instrument 32 is fixed to the reaction girder 18; and a displacement detecting portion of a displacement sensor 34 attached to a lower portion is brought into contact with a top surface 14U of the reaction pile 14. The result of measurement performed by the displacement sensor 34 is output into a controller 38; and the controller 38 controls a hydraulic pump 39 by determining the inclination of the reaction girder 18.
