Measurement and Evaluation System of Permeabilities of Rock Sample and a Rock Mass by Using Heterodyne Frequency, Transformation

本研究的目的是建立岩石样品和现场岩体渗透率的测量方法。渗透性是掌握和预测岩体性态的重要特征之一。在这项研究中，1)岩石剪切试验中岩石物理性质和水力性质关系的测量与考虑的研究。2)晶体结构岩体渗透率测量方法的研究。研究结果如下：1)明确了剪应力作用下不连续岩样的力学性质和水力性质的关系。2)指出了现场岩体的一种特征可以通过下一步内容来测量的可能性。我们产生了可以控制波的频率的地震源，而不是衰减到一定距离的地方。我们研究了一种将岩石渗透率与穿过岩石的波的频率特征联系起来的理论。我们使用震源，并研究了应用外差技术从波散曲线测量低系数岩石渗透率的方法。

A purpose of this study is to establish the measurement method of permeabilities of rock samples and in-site rock masses. Permeability is one of the important characteristics of rock masses in order to grasp and predict the behaviors of the rock masses. In this study, the next contents were examined.1) Study on measurement and consideration the relationship physical and hydraulic properties of rock in a shearing test of the rock.2) Study on measurement method of permeabilities of a crystalline structure rock masses.Results of the study are as follows.1) We made clear the relationship of mechanical and hydraulic properties of discontinuous rock samples under shear stresses.2) We pointed out the possibility that a characteristic of in-site rock masses could be measured by the next contents.We produced the seismic sources that could control the frequencies of the waves that do not damp to a distance place.We examined a theory to relate permeability of rocks to frequency characteristics of the waves that pass through the rocks.We use the seismic sources and examined the method to measure permeabilities of rock masses having low coefficient from dispersion curves of the waves by applying heterodyne techniques.
