[0018] The device for testing the three-dimensional stress state inside concrete and the testing method thereof of the present invention are described in conjunction with the accompanying drawings.
[0019] The device for testing the three-dimensional stress state in concrete and the testing method thereof of the present invention are based on: the stress state of a point in space is expressed by three normal stresses and three shear stresses totaling six stress components, so at least six mutually independent The test element to determine the state of stress at a point in space. The invention performs equivalent transformation on several edges of the regular tetrahedron to meet the operating principle and environmental requirements of the one-way stress meter, thereby being used for the stress test inside the concrete.
[0020] The structure of the device for testing the three-dimensional stress state inside the concrete of the present invention is that the three-dimensional ...
