网页2020年2月6日 · Based on the concept of damage, Fossum et al 10, 11 and Chan et al 12 introduced the damage into the constitutive model describing salt rock and proposed a multimechanism coupling model of salt rock creep and damage fracture-MDCF Model, which can well describe the creep damage characteristics of salt rock.
Experimental Study on Creep Properties of Deep Impurity Salt Rocks
网页1 天前 · As the pace of salt rock storage construction in China accelerates, suitable shallow storage sites are becoming scarce, as such, the utilization of deep salt deposits is a foregone conclusion. However, as salt deposits in China all contain a certain amount of impurities, triaxial multistage loading creep tests for deep salt rock with varying impurity contents were carried out to study the ...
