The mechanical behaviours of rockmass in high slope engineering have close relations with various factors including its surrounding stress environments and physical conditions as well as the time-space effects of rockmass deformation in unloading zones neighbouring slope surface due to excavation in construction work. In this paper, the study on stability of the black granite diorite, a kind of brittle elasto-viscous rockmaas,in the unloading zones neighbouring slope surface of an artificially excavated high slope engineering work would naturally reflect the following three respects of mechanism from the viewpoint of damage-fracture mechanics:(1 ) the unloading damage-fracture effects of rockmass neighbouring slope surface,resulting from excavation work of the slope by parts ;(2)the time effect deformation and creep shear expansion during development of the damage and fracture of rockmass in unloading zones neighbouring slope surface under action of the secondary stress field after excavation ;and(3) the ground dynamic action relevant to the sudden and sharp release of stress energy from the brittle elastic rockmass in overstressed region due to. excavation.This paper focuses on rockmass stability of the artificially excavated high slope of the shiplock engineering work of the Three Gorges Project of Yangtze River. A brief description of the progress in research work involved with the above-mentioned first two respects is presented.
