Variation of Pore Water with Deformation Behaviour of Rocks under Various Effective Confining Pressures

Development of a transparent triaxial cell and observation of rock deformation in compression and creep tests

“…The water volume then reaches a maximum near the peak strength; thereafter, the slope of the curve becomes negative, and the water in the reservoirs gradually returns to the specimen. This water behavior shows approximately the same trends as those reported for earlier experiments on changes in pore water volume and pore water pressure [13,14].…”
