Geometric and Mechanical Properties of Discontinuities of Rock and Its Characteristics of Flow

地下利用的主题是放射性废物处置的代表性，它增强了对破碎岩石质量研究水流特性的重要性。从这一点的观点来看，这一研究描述了由使用一种新的测试设备获得的characteristics，它开发了一种启用流水耦合测试的方法。每个花岗岩规格， 80·100·120毫米，用于测试，包括一个人工制造的半乳糖到岩石升降机平面。它是从配对测试中发现的，即该物种的渗透性下降，增加正常压力，增加了大量的剪切置换。这种剪切-流动特性同意与某些预测的细胞，采用理论和物理孔径的帐户，以及破碎表面的粗糙度。

The subject of underground utilizations that is representative of radioactive waste disposal has enhanced the importance of investigating water flow characteristics of fractured rock masses.From this point of view, this research describes the characteristics obtained by using a new testing apparatus which has developed to enable shear-flow coupling test. Each granite specimen, 80・100・120mm, used for the tests includes an artificially made fracture parallel to the lift plane of rock. It is found from the coupling test that the permeability of the specimens decreases with increasing normal stress and increases so much with shear displacement. Such shear-flow characteristics agree with some predicted ones, taking account of the theoretical and physical apertures, and roughness of a fractured surface.
