【摘要】 地震CT获得的结果是地下介质弹性波速度的空间分布,与电磁波CT相比,弹性波速度与介质力学性质的关系要密切得多,更有利于确定异常性质。以云南文山某水电站大坝为例,介绍了地震跨孔CT技术在复杂岩溶坝基渗漏探测工程中的应用及应注意的问题。更多还原

【Abstract】 The exploration result of Seismic Computerized Tomography(SCT)is the spatial distribution of elastic wave velocity of medium.Compared with Electro-Magnetic wave,the relationship is closer between elastic wave velocity and mechanical characteristics of medium,so SCT is more advantageous than Electro-Magnetic Computerized Tomography in determining the elasticity characteristics of medium.Exemplified by a dam of the hydroelectric station in Wenshan of Yunnan,SCT technology was applied to detect the water leakage path of the dam base in Karst area,and some problems that should be paid attention to in application were pointed out.更多还原
