... properties of the in-situ rock mass are induced. As excavations progress, pore pressure changes occur beyond the slope face, and, while some factors such as infiltration or recharge may increase the pore pressure, others may help reduce it. Consequently, understanding the relation between pore pressure...

... ABSTRACT The acoustic velocity-stress equation of rocks is important to underground stress or pore pressure prediction. The P-wave velocity has different dependencies on stresses in different directions. An improved model between P-wave velocity and stress was established. P-wave velocity...
