Mechanical and Permeability Characteristics of Basalt During Unloading Confining Pressure Creep Tests Under Coupled Hydro-Mechanical Conditions

This paper presents an experimental study on the mechanical behavior and permeability evolution of basalt, drilled from the dam foundation of the Baihetan Hydropower Station in China. Two groups of triaxial unloading creep tests under hydro-mechanical coupling conditions were conducted. Based on the...
