在单轴压力下对具有锯口面的岩石样品的破裂和摩擦滑动进行了实验室试验。当锯口面与轴应力方向垂直时(拼合样品),研究了岩石的强度,破裂形态和前兆。对于锯口面与加载轴成65°和75°的样品,发现在宏观断裂发生之前有粘滑现象发生。粘滞时的应力降和轴向位移的变化比断裂时要小得多。实验发现,在锯口样品中的断裂往往从锯口一侧发生,穿过间断面而向另一侧发展。本文还简要地讨论了这些结果的意义。 Laboratory tests of rupture and frictional sliding of rock samples with kerfs were carried out under uniaxial pressure. When the saw face is perpendicular to the axial stress (flattening the specimen), the strength, rupture morphology and precursors of the rock are studied. For samples with a kerf face at 65 ° and 75 ° to the loading axis, it was found that stick-slip occurred before the macroscopic fracture occurred. Viscous pressure drop and axial displacement change is much smaller than the fracture. It has been found experimentally that the fracture in the kerf sample often occurs from the kerf side and across the discontinuity to the other side. This article also briefly discusses the significance of these results.
