Generalized Variation Problem Of the Fractured Rock Mass Under the Linear Elastic Unloading Stage YU Li1 FU Ming fu1,2 　　XIE Zhi long1 (1.The Civil Engineering And Architecture of Nanchang University, 330031; 2.
The tensile stress was often produced when slope and underground engineering were excavation unloading, and the tensile stress increased with the increase of the structural size.
Tensile stress rock or rock mass can withstand is very small, deformation characteristics under tensile occupied an important position in evaluation of the stability of the slope and underground engineering.
