Variational Problem of Unloading Fractured Rock Mass

Abstract:

This article mainly introduced variational problem about stress-strain relationship of unloading fractured rock mass in the excavation. In this paper, research is carried out on variational principle of unloading fractured rock mass in the stage of linear elasticity.
