摘　　要：某古墓室位于华北地区石灰岩山体内,墓室采用反复加热和冷却煅烧而成。每逢雨季,墓室顶部、侧壁岩体多处出现渗漏现象,严重威胁到墓室本体及内部文物的安全。为解决墓室岩体的渗漏问题,对该墓室顶部及周边岩体进行渗透性试验研究,为后期抗渗方案设计及施工提供依据和数据支持。本次试验采用了回旋钻探、压水试验、全孔壁数字成像、井间CT等多种方法进行渗透性试验研究,通过多种试验结果的综合比较分析,查明了墓室渗漏的原因,为抗渗处理提供可靠的设计参数。An ancient tomb located in the limestone area in North China. The coffin chamber was made of repeated heating and cooling calcinations. There are several leakages on the top and side wail of the tomb during the rainy season, which will threat to the body of the tomb and the security of internal cultural relics seriously. In order to solve the problem of seepage in the tomb chamber, the permeability test of rock mass at the top and the surrounding is conducted for the design and late construction, In this study, the permeability property is studied through various methods, including：ratory drilling, packer testing, borehole digital imaging, inter-holes CT. Through the comprehensive investigation methods, after comparation and analysis, the cause of seepage in the tomb chamber is identified and the reliable parameters are obtained for impervious treatment design.
