摘要： 以某隧道工程压水试验为例，利用钻孔压水试验P～Q曲线对岩体裂隙特性进行定性分析。选取该试验孔三段压水试验成果，对岩体裂隙的发育程度、张开度、填充情况及受压情况下裂隙变化状态，进行综合分析与研究，并将分析结果与钻探取芯、波速测试成果进行对比和相互验证。

关键词: 压水试验, 岩体裂隙特征, 透水率, P～Q曲线

Abstract: This paper presents the packer test results at three locations for a tunnel project. The rock mass fissure is characterized by tested PQ curves.  The fissures in the rock mass and their openness, filling materials as well as their deformation under [JP2]the loading are extensively studied. The results are compared and verified with the rock cores and sonic wave velocity test results.

Key words: Packer Tests, Rock Mass Fissure Characteristics, Coefficient of Permeability, P～Q Curves
