Abstract

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
