摘要随着越来越多高水头电站、深部地下工程的建设，工程中面临更多渗透失稳风险，必须通过现场试验系统研究裂隙岩体的高压渗透特性和渗透稳定性。通过现场揭示和水–岩相互作用关系，探讨裂隙岩体的高压渗透破坏机制和破坏模式。基于多个高水头电站中的高压压水试验和高压渗透试验成果，研究高水头压力作用下裂隙岩体的水力劈裂、渗透变形、抗冲蚀性能、渗透稳定耐久性等特性。研究成果表明，高压条件下裂隙岩体的渗透特性会发生显著改变，变化规律和特征与所作用的水压力、应力赋存环境和物质填充情况紧密相关。

Abstract：With rapid construction of hydropower stations and deep underground projects under high water pressure，there are more and more seepage failure risks in these projects. As a result，the in-situ high pressure permeability must be tested and the high pressure permeability properties and seepage stability of rock masses must be systematically and thoroughly studied. In this work，according to the revealed phenomenon in field and the water-rock interactions，the seepage failure mechanisms and failure modes of fractured rock masses under high water pressure are discussed. In addition，based on high pressure packer tests or high pressure permeability tests of several hydropower sataions under high water head，the permeability properties such as hydraulic fracturing，seepage deformation，erosion resistance and long-term seepage stability are studied. The results indicate that：(1) The permeability properties of fractured rock masses can be remarkably changed by high water pressure. (2) The changes of permeability properties are quite correlative with water pressure，supporting environment of stress and fracture fillings.

Key words： rock mechanics fractured rock masses high pressure permeability test high pressure packer test permeability property
