摘　　要：利用电磁波井间层析成像（ＣＴ） 技术，查明核反应堆基岩裂隙、裂隙密集带和强—中等风化带的分布。研究同一钻孔不同特定方向剖面某些裂隙或裂隙密集带对电磁波吸收系数的变化特征，可以推测基岩裂隙带分布的优势方向。Using electromagnetic wave interborehole tomographic imaging(CT)technique,one can find out the distribution of fissures,closely spaced fissure zones and strong medium weathering zones in bedrock of nuclear reactor,study the variation characteristics of electromagnetic wave adsorption coefficients of some fissures or closely spaced fissure zones along profiles in different specific directions within the same borehole,and infer the preferred direction of the distribution of bedrock fissure zones.

关 键 词：层析成像 核反应堆 地基勘察 电磁波测井
