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。
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 underthe loading are extensively studied. The results are compared and verified with the rock cores and sonic wave velocity test results.
