摘要： A three-dimensional displacement measuring system measures the three-dimensional displacement of a mass such as rock. A first cylindrical member is provided as a displacement indicating device and is arranged on one side of a discontinuous surface, such as a crack, in a bore hole in the rock. The bore hole extends across the discontinuous surface. A second cylindrical member is provided as a displacement measuring device on the other side of the discontinuous surface and is free to displace relative to the mass and the first cylindrical member and is located opposite to the first cylindrical member.

摘要： A complete, three-dimensional stress state of underground rock is determined by a method which includes the steps of: drilling a rock to form a borehole with a substantially spherical bottom; deforming the borehole either by releasing the rock from the stresses by overcoring or by applying an external static pressure to the rock; and measuring displacements of the spherical bottom in at least xx, yy, zz, xy, yz and zx radial directions during the deformation of the borehole.

摘要： A method for measuring three-dimensional displacement of a mass comprises the steps of providing a measuring object placed on the end surface of the mass, for reflecting at least a fraction of three-dimensional displacement of the mass, arranging a displacement measuring equipment for free displacement relative to the mass and in opposition to the measuring object, and measuring three-dimensional relative displacement of the mass by detecting relative displacement of sad displacement indicative means relative to the displacement measuring equipment by the latter. The method is implemented by a three-dimensional displacement measuring system comprises a measuring object placed on the end surface of the mass, for reflecting at least a fraction of three-dimensional displacement of the mass, a displacement measuring equipment arranged for free displacement relative to the mass and in opposition to the measuring object, for measuring three-dimensional relative displacement of the mass by detecting relative displacement of sad displacement indicative means relative to the displacement measuring equipment by the latter. The method and system is suitable for measuring displacement of a rock across a crack.
