项目摘要
In order to propose the hydrogeological model, we try to estimate permeability tensor defined by crack geometry and wave velocity. The permeability testing method was developed by using newly introduced vessel for permeability measurement and high-accuracy pump, and the permeability dependence with coffining pressure was measured. Here, the confining pressure is changing 0 to 10MPa. Additionally, the crack geometry was estimated by the multi directional wave velocity using the developed crack geometry - wave velocity relation. In this study, crack density per unit volume and crack anisotropy could be estimate by the distribution of wave velocities. The estimated permeability is almost correspond with the measured permeability.
为了提出水文地质模型,我们尝试估计由裂缝几何形状和波速定义的渗透率张量。利用新引进的渗透率测量容器和高精度泵开发了渗透率测试方法,并测量了渗透率与围压的关系。这里,围压变化为0~10MPa。此外,使用开发的裂纹几何形状-波速关系,通过多向波速来估计裂纹几何形状。在这项研究中,单位体积的裂纹密度和裂纹各向异性可以通过波速的分布来估计。估计的渗透率几乎与实测的渗透率一致。
