Experimental investigation of triaxial compression and permeability of gritstone in geothermal environment

In this paper, the characteristics of microscopic failure and macroscopic mechanics of gritstone are studied experimentally under geothermal conditions. Different hydrothermal and cooling treatments are conducted to simulate geothermal environments. Permeability and triaxial compression tests of treated gritstone specimens are employed to obtain complete stress–strain curves and permeability and to discuss the mechanical properties of gritstone...
