DEFORMATION AND STRENGTH CHARACTERS OF JOINTED ROCK MASS UNDER UNLOADING STRESS STATES
卸荷应力状态下裂隙岩体的变形和强度特性

Unloading failure tests of jointed rock mass models are made under true triaxial condition using two kinds of unloading ways. The unloading deformation, failure and strength characteristics of jointed rock mass are studied and analyzed in two kinds of unloading ways.
