Abstract

The article presents the fracture test data of rock samples with the porphyroblastic, granoblastic lepidoblastic and laminated structure. The tests were carried out on lab-scale tester ASI-2. The test samples were subjected to uniaxial compression until discontinuity with synchronous recording of associated electromagnetic emission, load and displacements along the compression axis. The laminated rock samples in fracture show anisotropy of geophysical parameters and electromagnetic emission.

与岩石样本断裂有关的电磁辐射

摘要本文介绍了具有斑岩、粒岩、鳞片岩和层状结构的岩石样本的断裂测试数据。测试在实验室规模的 ASI-2 型测试仪上进行。测试样本受到单轴压缩，直到不连续为止，同时同步记录相关的电磁辐射、载荷和沿压缩轴的位移。断裂中的层状岩石样本显示出地球物理参数和电磁发射的各向异性。
