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