Description
technical field [0001] The invention relates to the field of rock conventional triaxial compression mechanical behavior testing, in particular to a deformation measuring device and method for a cuboid rock sample triaxial compression test. Background technique [0002] At present, in the conventional triaxial test of rock, the sample is generally a cylinder. However, it is difficult to determine the position of the cracks and defects in the cylindrical sample, so it is necessary to carry out the conventional triaxial compression test of the cuboid rock. The circumferential measuring device of cylindrical samples is generally a measuring ring composed of chains, while the measuring ring is not suitable for cuboid samples, mainly because the cuboid has edges and corners, which cannot guarantee the free rotation of the measuring ring, resulting in inaccurate measurement data. Therefore, the present invention discloses a set of deformation measuring device and method applied to...
