PURPOSE:To obtain the apparatus which can produce the state under the approximately same conditions as the real state, by using a model wherein footing is reduced to a fraction of the real size and applying an axial force and bending moment to said model. CONSTITUTION:A box, in which a specified amount of sand 11 is contained, is provided. A frame 12 is provided on said box. A first operating shaft 17 is supported by the frame 12. A first liftong body 33, which is supported by the frame 12 so that it is freely moved up and down, and whose lower end is contacted with a material to be tested 34 on the sand 11, is provided. A first load cell 26 detects the load when the first lifting body 33 is pushed to the material to be tested 34 by the first operating shaft 17. A moving beam 41, which is supported by the frame 12 so that it is freely moved in the horizontal direction, is provided. A second lifting body is supported by said beam 41 so that it is freely lifted and lowered and its lower end is contacted with the material to be teste 34 on the sand 11. A second load cell 53 detects the load when the second lifting body is pushed to the material to be tested 34 by a second operating shaft. |
